Problem: Smells like gas, strongest on the passenger side, exterior, after shutting off. The leak does not show up on the ground. Kind of smell it while driving, too. Smell increases while idling.

Backround: I recently replaced my fuel filter, but long after it was due. It was clogged and full. Looked likea mixture of chocolate syrup and coffee.

1.)What's the most likely source of the leak?Injector valve o-rings? I count 12 o-rings to replace (2 per injector + 2 on press regltr + 2 on fuel feed). All 12 look like a pain to get to.

2.) Do shops have leak detector or method to pinpoint the leak to a single injector?

3.) Are there any other suspects for the cause of the leak? Maybe the intake gasket? Gasline near the fuel filter.

 

May be.. but have you checked all the lines and everything? I see its a 95, so you may definately want to make sure the throttle body isn't leaking.

 

No, haven't checked the throttle body. Dealer diagnosis wasall 4 fuel injectors need to be replaced. I don't believe him so I'll probably start by replacing just the o-rings.
