Fuel cap leak

Post by Grant »

Got petrol leaking out when the tank is full and doing some fast cornering. Does anyone know of you can get the rubber seal and spring for the cap. Driving slowly with less petrol isn't the answer!!!

Thanks for the link Angus, I should look at this too. Got banned from the track at two different track events for throwing petrol out of my cap. My planned solution was only to do track events with less than 1/3 tank full...

Spoke to SJ Sports about replacement parts, they said changing them wouldn't necessarily fix the problem. Not filling it so much is probably the easy answer.

True that it may not fix it, but it may. At least if you attempt to fix it by means of a new small O-ring and rubber seal, you can reduce the amount that may leak, and filling only partial tank may be OK on a few laps of a track but it's a PITA for daily driving or a reasonably long run.

The replacements from Steve are plain and the OEM had grooves.... But if you change them it will definitely improve the leaking like Andy says. They are exposed to the environment so they have to changed regularly

if your old one isnt cracked, try taking it off and smearing Vaseline all over it and leave in a warm place for a day or two. I did and it made it swell and more supple so no more leak.
