Just had a chat with the service manager on the phone regarding the smell of gas during warm-up on my 91 SE. He says it could be caused by 2 possibilities: (1) old fuel lines or (2) fuel injector seals.
I've read from other posts regarding this and it is mostly caused by old fuel lines. Anyone had problems with the fuel injectors?

Thanks guys.

P.S. The car has been mostly trouble-free (new alternator & manifold studs) since we bought it brand new back in 1991 and now I am starting to think maybe it is time to sell.

 

Its normally a fuel line that is hard to access. You should have all of them done. Normally the fuel injector does'nt leak in the engine bay, unless someone botched the installation job.

 

I'm having the same problem in very cold weather. Is this a do it yourself job and if so what parts or supplies would I need. What type, size and lenght of tubing would I need. Thanks in advance.

 

Same problem??? Checked fuel lines but can't find any leaks. Seems unlikely its fuel lines because it goes away after engine warms up. Can you see around the injectors?

 

it is actually the fuel lines in most cases of gas smell...I had it too...

it happens in cold mornings cuz the lines contract slightly and crack (due to age) and let out gas vapors if not gas itself...when the engine warms up...they expand back to their normal diameter and the minute cracks close up so the smell goes away.

there was a detailed thread on this problem just a couple weeks ago listing the size and specs of replacement fuel lines.

The "SEARCH" function is your friend...use it a bit. try keywords like "fuel line" "gas smell" etc...
good luck with the fix!

I got a 91 SE. My fuel smell was caused by an injector definitely and possibly another as well. Not the news you wanted to hear, but a new set of FI's really makes a big difference!
