Fuel Petcock Question

Post by Albuquralque » Tue Oct 09, 2012 7:47 pm

I went to pull my manual petcock to check/clean it. As I was trying to get the fuel line off of the petcock, the whole brass fitting piece came out of the petcock housing.

It doesn't appear that there was any type of adhesive holding this piece in there. It seems to just have been pressed in.

Thoughts on reinstalling it? Just press it back in as far as it will go? Should I use some type of adhesive? JB Weld?

Some fuel proof sealer would not hurt. i would take a trip to a good auto parts store and check the Lock-tite products.

Mine came out the same way yours did last month. I just pushed it back in with my fingers. Hasn't leaked yet. But I do have a replacement Yamaha manual petcock sitting on the shelf for this Winter's to-do list.

Cheers,

Just a little aside about the petcock. I also switched over to the Yamaha one. When I was futzing around trying to get the little plastic filter off to cut down the brass intake tube to the right height out popped the brass tube filter and all.. Heya!!!! went and got my oem petcock and yanked that brass tube and filter out
and stuck it into the the Yamaha one and saved the new one as a spare tube and filter.

So I guess we can now be sure that Russian quality is equal to Japanese quality!

The press fit brass fuel outlet fittings do come out easily. They can be pushed or tapped back into the recess, or better yet, they can be slightly deformed by squeezing or gentle application of a Small hammer to make them slightly oval. Making them very slightly oval, instead of round, provides a bit of springy tension to increase the friction of the fit. Clean the fitting and recess and tap it back in.

If you have access to some Loctite-603, it would be about the best for this application. It is a high-strength liquid compound for press fit applications and is the one that is “tolerant of oil and other contaminants” like you might find in a fuel system. Sure, there are probably other sealants as well.

Take a small ball bearing that is larger then the hole. Place the ball over the top of the hole and hit it with a hammer. This will push metal down into the top of the hole making it tighter. This also keeps the hole round where as squeezing the tube deforms it and causes a possible leak path. Green wicking Loc-tite is also fuel proof and can be used after the tube is reinserted into the pet cock.
