Sounds like a win to me, Skin. I have absolutely no knowledge of aircraft repair so I wouldn't even think to go that direction for parts. My BIL is a aircraft mechanic, though, and I've hung out at the hanger a little. The small air cooled piston engines he works on do look remarkably similar to Harley engines with more cylinders.
Aircraft techs do love their Harley Davidsons.
One time I was looking for a front brake master cylinder rebuild kit and ended up finding the same basic master cylinder kit and brake pads listed under Piper parts for a Cherokee. I went to a small shop to check it out and sure enough, they were the same...but they cost more...I thought those things looked familiar!
I tried to get my petcock off (1997 FXDWG) and it stuck right at the top of the filter. Tried to pull on it and the filter separated from the petcock, leaving the filter hanging out of the tank. Since I didn't have a replacement I shoved the filter back into the petcock and put it back on. I have just bought the bike and the reason I removed the petcock was that while riding the bike it died. Found out the voltage regulator was bad and it was running on battery power only. Before I jump started the bike, I moved the petcock to reserve and it did start, but then died. I moved the petcock back to run and it ran fine. ??? So, while I had the petcock off (minus filter) I took the petcock apart and found the plastic valve inside the petcock was turned 180 degrees. So when I thought I was on reserve, I wasn't. UHG! Who does that? Anyway, I don't like the fact that vacuum has to be applied to the petcock for gas to flow (I know the vacuum is there for safety reasons if the petcock leaks, but how often does that happen and it's just another point of failure IMO), so I will probably replace it (after I dig the filter out of the tank) with a simple one that does not need vacuum.
IMO, a petcock is too simple a device to spend a lot of $$$ on, so I will try and find a simple replacement (without the need for vacuum).
Any suggestions welcome - including criticism about what a stupid idea this is. I've had more than 1 of those in my long life.
Suggestion: Pingel. As stated earlier in the thread: OEM is $90ish and the Pingel can be found for about $100.
Theres some cheapy ones on J&P cycles or elsewhere, but theyre cheap. The levers stick or the metal pieces are plastic and fail. Just do it right one time instead of regretting it later.
So, I'm looking at replacement petcocks and they almost all say they are size 13/16 or 22mm. The nut on my petcock is 1". Are they referring to the size of the tank outlet or am I missing something?
So simple - yet so confusing!
The vacuum isn't there in case the petcock leaks, it's there in case the float valve leaks, a very common occurrence. Every float valve either leaks or gets replaced prophylactically. Gravity, on the other hand, has never failed since the beginning of time. Those of us with manual petcocks can shut them off, but a vacuum one doesn't have an "off" setting; it uses the (absence of) vacuum instead. Where the "off" setting would otherwise be is "prime," which bypasses the vacuum shutoff so you can fill an empty carb bowl.

They are referring to the threads on the tank bung. I'm guessing your 1" measurement is the size of the hex on your petcock nut? If so, that's irrelevant.
Quick follow up:
I replaced my petcock with a Bikers Choice brand and it was a quality part. All brass with very nice chrome plating and a metal screen filter. The detents for lever positioning leave little possibility of the lever being in the wrong or partial position. Under $30 on eBay. I had to rip apart my original petcock screen to get it out. I guess the plastic was swollen.
