View Full Version : fuel tank pressure

22-05-2007, 17:30
when i removed the petrol cap from my williams fri, sat and yesterday to fill up there was a hiss sound as if a load of pressure had just been released from the tank! i havent driven it for a while but i don't recall this happening in the past.

the car has been of the road for 6 months, started and ran maybe once a month.

i ran it almost dry at one point. left it for a week, put a gallon of fuel in then attempted to fire it up. it would run for a couple of seconds hunt a bit then cut out. after putting another gallon of fuel in it ran ok.

i have replaced the fuel filter and theres no fuel leaks

any ideas or help would be great

tank breather pipe blocked ? solenoid valve faulty ?

it's happened with various amountsd left in the tank from the warning light up to just over a 1/4 tank. today when i unlocked the cap the pressure almost pushed the cap out of my hand.

i will check the breather in a min, where can i find the solenoid valve?
