Fix for leaking gas cap

[Grandpot]

This is a cheap and quick fix for a leaking gas cap.  It does not require any disassembly or mechanical skill.  Just find a 1 1/2" O ring and slip it over the latch area of the cap where the original gasket is.  No need to remove the original gasket.

I was concerned about how reliable it would be and if it would slip off so I have been testing it for the past three months and have not had any problems.

No more gas smell!!!

A little more info please? I assume that the 1 1/2 inch is the ID of the O ring. What is the thickness?

[itsallabouthim]

Is there a part number or specific brand name that can be mentioned at a auto parts counter?

[Grandpot]

The ID of the ring is 1 1/2".  The diameter of the ring cross section is 1/8".  The brand I used is Parker, but I don't have a part number.  I just used a ring I had laying around.

If you use a ring with too large a cross section, you will not be able to close the cap.

Thanks for the tip! I've gotten used to the slight gas smell in my garage over the years. I'll get an o-ring tomorrow.

Great fix. Thanks for sharing.

Is there a risk of the O ring falling off when refilling?

[salty1]

I would say yes unless the Oring was "tacked" down. Remembering it's there would help a bunch.

Got the oring from autozone today .99 cents if it works yahoo if not no big outlay to find out lol.

I've been running with this solution by Grandpot for almost a year now, it seems to be helping!  (For some reason, a chunk was cut out of the original gasket). 

[Grandpot]

For those that are concerned about the "O" ring falling off and into the gas tank, "Don't worry about it", as my cousin Vinnie would say.  I've now run this fix for over 10,000 miles with no more leaks and the "O" ring has never fallen off.

Damn, where were you two years ago when I gave up and ordered a new lid!! Now I'm lugging two keys around.

Even if the O ring did fall off, it's not big enough to travel through the fuel lines.   

Just turn the bike upside down and shake the O-ring out.... or you could wait until you take the tank off and do something like that with just the tank.

Do you think it would float?  ???

Mine is leaking some fuel onto the tank underneath the chrome bezel will this fix that problem too ?

[Grandpot]

Snohunter:

When it leaks from the rubber gasket on the cap, the gas comes out under the chrome bezel.  The O-ring should fix this for you.  It is exactly what mine was doing.

THANK YOU

Thanks for the tip.  But I needed a 1-7/16" ID o-ring, because the 1-1/2" was too big.

Pretty cool and thanks for sharing this.

Anyone here that replaces the o-ring could add the part number?

They aren't really replacing anything. They are adding a generic o-ring on top of the rubber gasket that is OEM.

I did my gas smell fix a little different. The smell got worse after I installed the tank bib under the bezel.
The rubber gasket is very easy to remove from and put back on the cap. Using gasket material, I cut out a round gasket to  fit between the cap and the rubber gasket.  Solved my problem and have not had any trouble since.
