Subject: Re: [E36M3] Strong Gas Smell?
Date: Thu, 10 Feb 2000 07:49:20 -0800

Suspect the fuel pump system. It's weak link is that the pump components entering into the top of the fuel tank are made of white plastic. The nipples that the fuel lines mount to are made of plastic. They often crack at the intersection of the nipple base/fuel sender top. You might not see a crack, but if you have a problem you will see fuel...lots of it... in a 1/2" deep puddle.

To diagnose:

  1. Remove your back just pulls out.
  2. Unscrew the left (driver's side) access panel to your fuel pump system components (right side is called "suction side", left side is "sender side" (silver about 6" round)...about three screws from memory
  3. Look for gas on top of fuel sender
  4. If gas is present, suspect plastic nipples at top of sender.
  5. If no gas found, do same on right side.

Don't smoke while doing this. I don't recommend doing the repair yourself...the # of labor hours isn't that much, vs. possibly getting a bad sender (& hassle of trying to return an installed part), not getting a warranty, not to mention the risk of blowing up.
