Routy is in full petcock war mode and he now he wants to "define petcock failure" as only a split diaphragm, which is the oldest time frame and the very rarest of the failure modes.
Then he wants you to prove you had ALL the failure modes ... and nobody but Verslagen or Serobot has ever kept a stock vacsucker around long enough to get them all on the same unit. The rest of us jump ship long before then.
He hates it when people say they simply got sick of dealing with the stock vac petcock due to the lesser issues, one of which is fuel starvation, running out of gas, false "empty" signals, etc.
He wants to redefine the fuel starvation as "low vacuum issues" which is fine by me -- then he has to research and figure out a way to remedy "low vacuum issues" which will be fun to watch him go do.
Wait until he asks everybody to put their Suzuki stock air filters back in place ......
Routy hates losing a petcock war, which is good because that makes him long lasting -- reminds me of eating a Brown Cow candy on a stick. A Brown Cow was a dark caramel bar on a paper stick that you couldn't bite through it, it was way too too tough and thick. You had to suck and lick it until it softened, then you could bite off a piece. This always wound up with your teeth stuck together when you bit into it -- movie time fun to no end.
You can run him off screaming if you just simply cheerfully list all the ways the new Raptor petcock is easier to live with and simply works better.
Just tell him how much better you like it, and why.
Reminds me of sprinkling salt on a snorkle snail (slug) -- you get some similar reactions.
