Title: Inline Fuel Filter - Help please! Post by saratovich on 05/24/08 at 15:20:35 I'm chasing dirty gas issues - needle valve (new two weeks ago) causing gas overflow and stalling. Tomorrow I'll pull the bowl and clean it and will likely be ordering a new petcock as well. I'm not going to flush the tank until the new petcock installation. But I want to install a fuel filter now so I can continue riding. The filter is often mentioned here, but not detailed that I have found in searching the old posts. I found a small filter at AutoZone, looked like it would fit just fine. Took it home and went to the manufacturer's website looking for flow numbers. I found out the AutoZone filter was for a Briggs and Stratton engine. I figured the Savage would need more fuel flow than a lawnmower. The area bike shops are closed today, so I wasn't able to get a filter there, but picked up a universal Fram filter at Fleet Farm. It was too long - not a lot of space to work with! What are you guys using for inline filters? The one mentioned in the Clymers is twice the size of the AutoZone mini? Source, Brand, part numbers and a picture would be appreciated! I'd be most interested in LOCAL procurement vs. a web order. Thank you. |

Title: Re: Inline Fuel Filter - Help please! Post by verslagen1 on 05/24/08 at 17:41:42 car filters are meant to be pressurized. either go to a bike shop or a lawnmower shop. get a clear one so you can see what crap is in there. |

Title: Re: Inline Fuel Filter - Help please! Post by Oldfeller on 05/24/08 at 18:31:47 Ah, you are going to provoke the fuel filter wars all over again with your innocent question. Shame upon your punkin' haid for doing this turrible turrible thang again !! ================================= There are 3 positions taken by the various fuel filter warriors around here. 1) you don't need no stinking fuel filter. Petcock assembly has a screen on it already. 2) get any sorta little bitty filter that will fit in the fuel line that currently exists. Anything is better than nothing. 3) use what fuel line that exists as a lead in to a larger clear 10 micron pleated paper filter fuel filter (Autozone sells them) which gets tucked up under the seat where you can still see it and you put in a new piece of hose from the exit side of the bigger filter running back to the carburetor. Big ain't bad nor hard to do either. Note how the new return hose has nice broad bends to it so it won't ever pinch itself off in use. Big clear 'ol thang will show you condition of your fuel, graphically illustrates any vacuum petcock issues you may come up on, traps any condensation water from the tank and shows it to you and it also has enough trash holding capacity so it will last for years & years & years without plugging up. Plus you can SEE what's going on .... big plus on this point when you are broke down by the side of the road doing "what the frik" troubleshooting. ================================== The cruxt of these three positions is "do you really want to remove all the small trash and water from from your gasoline or do you want to only take out the big chunks?" Weeeeeehaw !! Let the fuel filter wars begin !! :o Oldfeller http://www.hunt101.com/data/500/medium/fuelfilter.JPG |

Title: Re: Inline Fuel Filter - Help please! Post by barry68v10 on 05/25/08 at 04:55:11 The Briggs and Stratton filter is likely a mesh screen and will flow plenty of fuel for the Savage. We're not talking about a top fuel dragster here...nominal flow rate will be about 1gal/hr or so on the Savage, never higher than 3 or 4...I'm confident any gravity feed filter will flow quite a bit more than that, but you can run your own test if you're still worried. |

Title: Re: Inline Fuel Filter - Help please! Post by Oldfeller on 05/25/08 at 05:22:46 What's wrong with a healthy dose of water? Durn it, I pays near on to $4 a gallon fer pur gasoline and that there stinky little rascal runnin' that service station is mixin' water inner his product ON PURPOSE? When pressed, he sez the alkyhol his distributor is a lacing into his truckloads (legal, but he's not tellin' nobody nether) is hygroscopic, whatever that there means. That's cheat'n !! I use my little truth bulb to catch'm at it. ::) ============ http://www.freepatentsonline.com/4158551.html (you got to scan down several pages to get to the good stuff) Seriously now, alchohol (and the water that comes with it) in cheap gas is a clear and present danger as our scoot wasn't designed to handle alternate fuels. Hydroscopic fuel additives such as alcohol will promote tank rusting and other bad things in your fuel system which can lead to rust and "strange trash" in your tank. You do want to stop all this "strange" before it gets into your carburetor, now don't you? 10 micron pleated paper is the cat's meow for stopping various forms of strange, especially when combined with all them fine alcohol-bound water micro droplets. Check out my current "gasoline" in the picture show above -- pretty murky and nasty looking, isn't it? A certain amount of alcohol is currently permitted as an "anti-knock additive" even in non-alky gasoline so you can't blame folks for thinnin' out their mix a bit with $2.50 a gallon anti-knock additives (and that little bit of extra H2O) since it is legally permitted now-a-days. Ammoco doesn't do this, nor does BP or Exxon. Your local Quik Pic who generally has the best gas prices locally, you betcha he does .... his distributor does it for him before he loads the tanker truck. Emulsified alcohol bound water in micro droplets, ain't that a kick? And you thought you just had to worry about condensation in the tank and slugs of water from bad leaky underground tanks ..... |

Title: Re: Inline Fuel Filter - Help please! Post by barry68v10 on 05/25/08 at 08:29:15 Great stuff O.F. but I don't think your little paper filter will hold more than about .5 to an ounce of water. I'd guess within a few to 10 tank fulls, your little paper filter is saturated with water, the rest of the water is headed thru your carb anyway. Yes, alcohol. Interesting chemical. I think mixing alcohol with petrol is the dumbest idea ever...at least for the consumer. Anhydrous alcohol (alcohol with no water) doesn't stay that way unless it's completely isolated from ALL moisture including air and only gets that way through chemical reactive means! You can't distill alcohol to 200 proof. I say, either burn 160-170 proof alcohol in an engine DESIGNED for it, or don't burn it at all. OK, I'm off my soapbox now... ::) Let the "fuel filter wars" rage! ;D BTW, Oldfeller, I love you man! :-* |

Title: Re: Inline Fuel Filter - Help please! Post by Oldfeller on 05/25/08 at 13:32:25 How how did you like the full text of the patent to put water in gasoline using the alcohol and other surfacents to keep it in micro emulsion suspension? Illuminating, wasn't it? Got to keep scanning down the pages to get to the percentages of H2O that alcohol gas can be coaxed into carrying. Amazing, ain't it? That's a lot of water. Now you know why some gas is slightly cloudy looking nowadays instead of crystal clear reddish-tan like it used to be when we were kids. What happens to the water in the filter? Why, eventually you get some good alcohol laden gas that isn't intentionally water laced, and the trapped water "evaporates" as the fresh alcohol flows through it picking up water molecules as it goes on by. The rusty dirt that stays behind makes the little dark slick that develops on the lower surface of the filter bowl. BTW, Wal-Mart sells the clear filters (Fram brand) in their auto departments for $3 and $4 (two different sizes of clear filters). Either would work just dandy. |

Title: Re: Inline Fuel Filter - Help please! Post by saratovich on 05/25/08 at 18:26:02 Well the story continues . . . The B&S filter was clear plastic with a round pleated paper filter . . . any way it was a no go. Bought some fuel line to try with the FRAM filter today . . . heh, heh the fuel connections are 3/8" vs the 1/4" filter and fuel line I bought. AP stores are open tomorrow, will take a gander then. ;) ;) |

Title: Re: Inline Fuel Filter - Help please! Post by Sandy Koocanusa on 05/25/08 at 18:28:19 I wouldn't bet a vital organ on it, Saratovich, but I think the fuel line is 5/16. Double check before you buy any 3/8. |

Title: Re: Inline Fuel Filter - Help please! Post by Oldfeller on 05/25/08 at 20:05:17 http://www.hunt101.com/data/500/medium/hose.JPG Now now boys, you jest gotta pretend to understand how turn of the century Society of Automotive Engineers thought about sizing tubing and hoses. They copied the Brit system which was based on measuring the size of the nipple the hose went over. Then you got to savor the flavor of the METRIC nipple size Suzuki had to deal with. But, since this here is a filter war (which is actually a re-boil of some old filter wars) I done KEPT my original bits and pieces all together and I can snappy a pic of what they looked like (along with a digital caliper stuck inside the OEM tubing which is nowhere as well made as the nylon braced tubing I used to make the return trip from the far end of the clear filter. Way she's spec'd is quarter inch ID (6mm ID metric, 0.250" English) which is a wee smidgin tighter than the OEM tubing really was at 0.2675" on the unexpanded unused end of things, taking my best guess at sticking a caliber inside a piece of movable rubber tubing, anyway. Get yourself a passel kit full of various sizes of quick connect hose clamps like I did and you can make durn sure nothing ever leaks on your filter installation job. Hates it when my $4 a gallon gas dribbles out, I do. And she might if you upsized the hose to .3125" on the ID (5/16). Better to fight a bit tight than try to loosie the goosie. <hee hee> Oldfeller |

Title: Re: Inline Fuel Filter - Help please! Post by Gort on 05/25/08 at 20:52:59 The problem I faced with trying to use 1/4" hose on my '96 Savage is that the hose had to be forced over the fittings to the point of distortion. Distorting fuel hose like this leads to cracking when the hose dries out with age. I then went to 5/16" fuel injection hose which fit VERY snug, and used 13-15mm fuel injection type hose clamps to secure it. This arrangement along with an in-line fuel filter resulted in a very strong, secure set-up that has never leaked. |

Title: Re: Inline Fuel Filter - Help please! Post by Oldfeller on 05/26/08 at 04:52:49 Ak! Douse me with hygrozene and gimme a match -- I've done hit me a Minnesota woman with a peter joke reference and done gone down in smokey flames when she gracefully handed it back to me with her caliper all a buzz'n like that ..... Aaahhh, for the shame of it. Never never swap jokes with a woman, you'll lose every time. I am mortified and defunct. (P.S. they likes to hide behind them gender non-specific names and surprise you when they stick your feet in your mouth (or get you to do it for them, as the case may be) And now I bet I'm gonna get me a lesson on patronyms or some such further embarassment to complete my total flaming destruction ... no proper woman would ever admit to an intentional bushwacking anyway. Plus (as all married men know) they gotta get in the last word .... :-[ |

Nah, my dial caliper crapped out, the replacement caliper is digital . . . it uses batteries. ;) And a few simple tasks this week have required a lot of measuring! Saratovich is male. Saratovna is female. Patronymic names are based on the given name of the father. The suffix (meaning either "son of" or "daughter of") is added to the father's given name. Males use -[ch1086][ch1074][ch1080][ch1095] -ovich, while females use -[ch1086][ch1074][ch1085][ch1072] -ovna. I think you were up too late staring at the computer screen! ;D |
