Check all your rubber fuel lines, front and rear. If you can, get it on a lift and literally poke around by the gas tank. I had my lines rotting (it had sat for 2 years in someone's yard before they got it running and sold it to me) and had this same issue. Couldn't find any drips under the car, but on the lift I discovered the hairline cracks letting gas and fumes seep out and evaporate. Also, a dirty MAF will make the car run rich, especially on cold mornings, and you might smell a bit of gas there too. Hope you find the problem.

Honesly bro I been driving these cars for years and not figured where that smell comes from. All my rubber lines were fine. All my exhaust components were new. My smell smelled like a mixure of exhaust and gas.

Under the back %seat by the fuel pump theres a o-ring the keep fumes out.im 100% sure it that

I agree. If the o-ring for the fuel pump lets the smell leak out. replace it with one from Greg V and you should be set.

who is greg v....??? as i am in australia...

i had/have the same problem. I smell fuel inside my car sometimes and sometimes i don't. and i smell it outside sometimes. so agreed with the above.

#1 check your fuel lines, even if you don't think they're leaking but they probably do have spider cracks considering it is almost 20 yrs old if it hasn't been replaced
#2 o-ring in the fuel tank cover holding the fuel pump, had big issues with trying to seat it properly so the fuel wouldn't leak.

but who or what is greg v

In the vendor section of this forum greg v owns Gspec preformance, or you can go to gspec.com, but most of the time it is best to email him directly. [email]Sales@gspec.com[/email].
