[DML] Re: Crap in fuel pump + normal pump sound?

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

As the pump pressurizes the fuel system it will slow down and the
sound changes, that's normal. The timing is because it takes some time
to pump up the accumulator. As for the fuel screen that the pump
ingested that is BAD. For it to have done that the screen must have
been completly blocked with dirt so the pump literaly sucked the
screen and the dirt right in. After that there was no screen to stop
all the other dirt so it also went through the pump. The pump is
probably on borrowed time. Maybe you don't have to change it
immediatly but I would order another to have on hand so when it does
die you can put it right in. I would scrub the tank clean with acetone
and all the parts inside. Make sure it is scrupulosly clean. Drive the
car and use up at least 1 tank of gas then replace the fuel filter.
After that check the pattern on the injectors, they should be OK but
with that much dirt having gone through the system they should be
checked just to be sure they are OK.
