Taz_Rx Posted June 8, 2009 Report Share Posted June 8, 2009 For starter...... Is it under PRESSURE or VACUME!? Your probably on the right track with the charcoal canister though. Quote Link to comment Share on other sites More sharing options...
LittleRedSpirit Posted June 8, 2009 Report Share Posted June 8, 2009 For starter...... Is it under PRESSURE or VACUME!? Your probably on the right track with the charcoal canister though. Either the breather line or charcoal cannister is blocked. Have a very close look at all the fuel lines with the car running on a hoist. Check for leaks and stuff.

Evan G Posted June 9, 2009 Author Report Share Posted June 9, 2009 its under pressure like PSSHHHHHHH. i remove the purge vacuum line that goes to the carb, suck on on the hose and got high, so purge valve is working and the fuel line is all cracked to the fuel filter but not leaking???? no farking idea how to test the carcole canister it self? more surgestions?

irokin Posted June 9, 2009 Report Share Posted June 9, 2009 It will go PSSHHHH when its under vacuum too but that isn't abnormal for a fuel tank. My corolla does it, my silvia does it, my brothers honda jazz does it and my familys old commodore did it too. Quote Link to comment Share on other sites More sharing options...

Taz_Rx Posted June 10, 2009 Report Share Posted June 10, 2009 HOW do you suppose the tank is getting pressure in it? what is making the pressure? Quote Link to comment Share on other sites More sharing options...
sammo[RL] Posted June 10, 2009 Report Share Posted June 10, 2009 My girlfriends 2003 focus did that every time i opened it. most of the time it did it more often when the tank was near empty. The rolla does it to. I think its normal.... Quote Link to comment Share on other sites More sharing options...

Old fella Posted June 11, 2009 Report Share Posted June 11, 2009 well i first noticed it at the bp, open the cap and "PSSSSHHHHHHHHH" then my old man complained of a bad fuel smell.... any suggestion on a test procedure? i personally think its the charcoal canister is blocked??? thanks people Evan Mate, my daily s a petrol Landcruiser and I never had a tank pressure problem until I started using the cheaper fuel with Ethanol added. Now it pressurises all the time, but has no ill effect other than a faint fuell smell from time to time. Just to demonstrate what happens to fuel inside a fuel tank, grab a plastic soft dring bottle and put a little bit of your fuel in it and shake, or even leave it in the sun for a short while. You`ll be amazed how much pressure it builds up all by itself. I`m not sure if corolla`s run a vented fuel cap or not, but that is worth checking also. See ya and good luck.
