Raptor petcock leaking at tank/bolt interface
07/11/15 at 03:48:31

Hi,

I have recently installed a raptor petcock and it has been leaking ever so slightly since I installed it. Today I decided to try and fix it, but seems it just got worse even though I put a little bit of liquid gasket on the o-ring that lies against the tank.

The tank surface has been thoroughly cleaned for residue and so on, so I don't think the leak is at the o-ring.
I have a feeling the leak is through the threads, but I am not sure on the best approach to fix that. I've considered putting some liquid gasket on the thread of the bolts and see if that helps?

Any ideas/experiences from you on how I can go about fixing this would be most appreciated...

There ought to be a cork washer on each of the bolts. The bolts should be just snugged down so the washer isn't crushed. You can make them easily from cork jointing from the motor supply place or offcuts from a car gasket set. That worked for me. maybe Stag might seal it, I don't remember if the rubber gasket isolates the bolt holes from the fuel passage.

Note the o-ring is around the perimeter of the surface that mates with the gas tank. Kenny G

I had a look at the old bolts and could see something resembling gaskets as mentioned above. For some reason I can't get off those gaskets easily, so I will try with some small o-rings and see if that will work. I'll post a follow-up once I've tried it
