ongoing issue..

This is a topic i posted in the "other forum" but haven't been able to find and answer to my problem yet. hoping for better luck here...

Now I know this topic has been discussed extensively in this forum, I know because i have been searching through all of them, but I'm looking to pin point my problem better. since last summer I have been getting a fuel smell inside the cabin only after the car
has warmed up and only when I really step on the gas.
now I have replaced the fuel pumps, fuel filters, and checked all the lines. Even the ones way back behind the engine. Checked the fuel rails as well.
This all started last summer after i had all this work done. i also had the caps rotors, spark plugs, valve cover gaskets and removed the cats. I thought that maybe it was because of the cats but its not exhaust smell its definitely gas and only when the car is warmed up. Any suggestions?

the only things left that you haven't listed.
Have you checked the fuel lines on top of the fuel tank? How about where the rubber fuel pump hoses connect to the hard metal line right under and beyond the access hole for the pump carrier?
These are all good spots for the fuel to be smelled...

I'm going to replace to injector rings tomorrow and someone mentioned the charcoal canister. I'm going to try that but do you think with such low kms that it could be a possibility? and wouldn't the smell be all the time instead of only when I've been driving it for more than 30 mins

oh and i did check the lines on the fuel tank and the ones in the access hole. there are no signs of fuel there. the smell seems to only come about when under pressure from when i open full throttle

Did you check them personally yourself?

The most probable casue has alsways been either the old style fuel line in the rear cross over rubber tube [it is right next to the cabin air intake filter] or O-rings on the presure regulators or injectors themselves.

o-rings, since the fuel rail will be under the most pressure when vacuum to the regulators is cut at WOT. Also, did you check the return line to the tank, over on the right side of the firewall? They don't usually leak, no pressure, but it's the only one you didn't mention.

Also make sure your clamps are tight on the left rear of the engine where the gas lines come up. May not be the problem, but on my car everything looked fine, but I was able to slightly rotate the fuel lines, and tightening them up solved the problem. I later replaced them with new hoses and clamps when I had the chance. Good Luck.94 850CSi

thanks to everyone for all the suggestions. i have some o rings on the way from autohausaz and as soon as the get here I'll change then all and let you know the out come. I have check most of the lines including the ones by the firewall. we'll see...
