[DML] Re: Stuck in Omaha-Loud noise in Accumulator

["Harold McElraft" <hmcelraft@xxxxxxx>]

The noise is probably the fuel pump - If this is the case, when you 
start up the car after the fuel tank cools over night or a fresh 
fill-up the noise should disappear.

This is caused by the engine coolant lines being close to the fuel 
tank. When the tank expands it expands against the coolant line 
compounding the heat expansion and the noise. I think most owners 
have probably experienced this at one time or another, especially on 
long trips. It can be annoying. First time I experienced the hum it 
was so loud I couldn't hear the radio. I thought for sure the fuel 
pump was going.

I have taken the fuel tank out and rewrapped the coolant lines and 
adjusted the position of the tank, etc. just to have the noise 
return a few years later. I did a rewrap just before PF and all was 
well - but the other day I was way down on fuel after a long drive 
and started to hear the noise - filled up it is gone - for now. BTW 
the fuel pump is fifteen years old - and been out twice for 
rebooting. Pressures are all in spec.

Bottom line - if this is your problem you can drive on without fear.
