I just recently replaced the petcock on my TRX250EX. After i bolted the petcock to the gas tank i added gas to the tank to see if the petcock leaked. I noticed a gap between the petcock and the tank that is about 1/8 of an inch big. Gas comes out of this gap and im wondering if anyone knows how i could fix this problem.

Could you send a picture?? Possibly...... make sure you don't have an extra seal from the old petcock in the way.

I removed the old washer due to it being old and having cracks in it and replaced it with a new washer.

Would you mind sending a pic. They always help
Also what year is your bike?

Did you use thread tape or sealant when you installed it?

 

[Andy98710]

I will post a picture of the problem and it is a 2007.

 

[Andy98710]

Thought about using sealant but not sure what is the best kind to fuse the metal to the plastic without the gas eating threw the sealant as well.

I've never used thread tape before on my petcocks. But that's a cheap fix if it works.

I had thought about using a bigger rubber washer to use to close the gap

Your old petcock. Did it have this same problem? Are you sure its the same petcock?

 

[Andy98710]

Yea i took the old petcock put it back on and it is still leaking gas not even sure how the gap happened because a couple days ago it was holding gas fine with the old one. It could be the new washer i used it could be to thick and not allowing it to seal all the way. I will have to take a look at it closer when i get back to work on it later.

Just curious. Why did you remove the old one?

 

[Andy98710]

The reason i replaced it is because it wasn't rode in over 6 years and i started to clean it up cleaning carb and gas tank. I noticed that gas was not coming from the gas tank and i figured it was the filter that is on the petcock i took the old one out and noticed that the filter and the brass tube was eat down due to the gas sitting in the tank for so long. i was unable to replace just the brass tube i had to buy a whole new petcock.

Makes sense. Just was curious. Send us some pictures when you get a chance

Here is a picture of the gap between the gas tank and the petcock

There is nothing sitting between the petcock and tank?

Might be a silly question, but is the petcock installed the right way up?

Can you also post a link to the add where you purchased it?

Nope there is nothing in there but an o ring that sits around the petcock filter and it is installed the right way

Looks to be closer on one side, is there a gasket or something between the steel and plastic?

 

[Goober]

After looking at the IPB I have to wonder if your bolt gaskets aren’t seated into the tank mounting base. If you’ve mushroomed the gasket then I see you would need to remove and reseat them

is that an after market petcock ? --- if you are tired of messing with it , take 3M-5200 and apply it to the base of the petcock , tighten it up and let it be cocked , let it cure for 24 hours at 70 degrees and forget about it
