Re: [DML] Fuel Pump Noise

I have always believed that keeping the fuel tank from dropping below half full will prolong the life of any intank fuel pump. Heat is the great enemy of any electrical device. Adding fuel that has been stored underground and is around 55 degrees will cool down the fuel in the tank. The full tank will also take longer to heat back up. I have a 1978 Eldorado that has been in our family since 1980. It has a 27 gallon fuel tank and to my knowledge it has the origional fuel pump. I have no proof that my theory is valid, but there is little downside to frequent fill ups even if I am wrong. Your lady will appreciate the stops. When I passed 50 I began to look forward to filling my car's tank and emptying my own.

As a D owner since 1982 and active on the list since
its inception, you might think I'd have all the
answers. Not even close. One problem that has
irritated me off and on since I first owned a D is
that damn fuel pump noise.

Now, when I go through Vegas on the way to SoCal and
hit 102º on Las Vegas Blvd I say, "Okay" it's the heat
and, sure enough, if I refuel and get some nice cool
gas from the stations underground tank, the noise goes
away - - for a while.
