[DML] Re: Fuel Accumulator

["denverdelorean" <denverdelorean@xxxxxxxxx>]

I just dont see how the sound could be coming from the pump.   I 
literally had it out of the car in my hand pumping gas to the 
engine.  ther was no excessive vibration or noise coming from the 
pump.  but there was still sound coming from the transmission area. 
Could sound really be transmitted through a rubber hose that 
loudly?  AND it is a brand new pump.  The problem also dissapears if 
the car sits over night.
