Re: [DML] Fuel smell

[Warren Wallingford <warren@xxxxxxxxxx>]

The advice you got was pretty much on the money.  I always counsel 
changing the gas cap first, especially since the smell is worse when the 
tank is filled.  Rod mentions fuel around and on top of the pump.  This 
is often caused by fuel seeping into the boot around the return pipe. 
It may also come from a cap nut that is not quite tight enough, a 
notched copper washer, or a loose clamp around the outside of the boot.

Deloreans have been plagued with fuel smells since they came out.  A 
popular remedy in the early days was to block the hole in the fresh air 
manifold that's located in the fiberglass body just above and to the 
rear of the where the fuel pump is mounted in the tank.  I doubt that 
this very effective by itself, but there was one dramatic unintended 
consequence.  That hole is the drain for that manifold.  All the water 
that runs down the windshield and through the screen goes into that 
space and is supposed to spill out onto the fuel tank and run to the 
ground.  That's why the cover seal needs to be in place, btw.  In a big 
rain, the manifolds with the improved ventalation filled up with water 
until full, at which point water began to run out of the fresh air vent 
in the fan motor area and onto the passengers feet and right side 
carpet.  This can happen naturally if a Delorean is parked under a pecan 
or any tree that drops stuff regulaly.  The leaves drop into the 
manifold and collect at the drain, blocking it.  Then would come the 
rain and the wet feet.  Next time you're in the area of the fuel tank, 
take a look at that drain hole.  Pull all the debris out of it.  If 
there is tape or some improvement, take it off.  Your carpet will smell 
better.
