Fuel Sending Unit Leaking

[mbradford99]

my bike has developed a leak in the fuel sending unit. It appears to be leaking from one of the bolts that holds it to the tank.
I have tried to tighten down, but still leaking.

I'm assuming gasket is bad, wondering if there is some kind of sealant (liquid gasket, permatex) that i could use to stop the leak.

anyone have any luck doing this ?

or maybe getting some gasket sheet and fabricating a replacement.

if all else fails, i can go to bike bandit and order.

thanks in advance.

If you know that it's the gasket...get a new one. Sealants have never worked for me and as a rule, I won't use them in conjunction with the fuel system. My .02

MOST of the stock petcocks use an oval ruber Oring as the gasket. If its no longer holding fuel, its probably time to toss the oring, however, at this point, you may be best served to REPLACE the entire petcock. Yeah, its working now (is it?) but if the oring is old enough to fail, then likely so are the diaphrams inside the petcock itself. You are dealing with highly flamable liquid right around the crotchal region.... Liquid type sealants are probably NOT a good idea for a fix either..

Why change the petcock o-ring?

He said it's the sending unit gasket that's leaking.

I just swapped my sending unit from my bad tank to my good one, and It looked to me like that gasket was on there good, almost part of the tank. I think you'd be best off getting an oem one from a dealer, versus trying to make one, or repair it especially when it relates to fuel, and being in contact with it continuously. ..just my 2 cents

Heck If I can figure out how to get the one off of my leaky tank, you could have it....it never leaked there for me.

I believe they are rubber seals.
