my car reaks of petrol, especialy on hot days, & after 15 or so minutes of driving with the c/c in fresh air the fumes start comming inside...

Its not a fuel leak, because ive checked. it seems to be coming from where the 2 hosed plug connects to the charcoal canister. there is some play in its connection. i cleaned the O ring in there and it made no difference.

The purge valve has been replaced under warranty as it was stuffed. but im still having petrol high's everytime i drive my car!!

1) When does the purge valve operate?
2) Why would i be able to smell it inside if the charcoal cansiter is under the front left wheel arch?

Its no danger, i just want to get rid of the smell!

thanks

*if its a carby type canister setup* the canister has numerous lines going to and from the fuel tank .. its possible one of the lines has a leak.

If its EFI I am not sure what the go is at all with the charcoal canister

Geeee, thanks for all the reply's....

It turns out.. hmmm your not supposed to fill the fuel tank right to the brim... this was causing my charcoal canister to be full of petrol!!

I will know not to be such a knob in future..

I didnt know it was bad to fill the tank right up.. oh well, i learnt something new..

In mine (efi) its very basic...

1 hose from fuel tank, then into 1 way valve, then into top of charcoal canister connector. Then vacume line from upper intake manafold (v8) goes to purge valve solenoid, then into bottom connector of charcoal cansiter connector.

I will inspect the hoses too, thanks

Hi Fairlane Boy,

The strategy for Canister Purge is; Off at from cold start up to medium loads when cold and also off on decelleration, On at medium to full load when warm.

It may take a while to unsaturate your canister. If you find it is still giving you the shits(vapours in the cab), take it out of the car and leave it in the sun for a day. This will evaporate all the remaining fuel. Or you can give it heaps everywhere so the EEC turns on the Purge Valve and draws all the vapours out.

Pete.
