Fuel pumps dying one after the other

["Wm. Josiah Erikson" <scirocco@insanetechnology.com>]

Hey all,
	My '84 Rabbit eats fuel pumps, I would loved some opinions on why.
I've had five fuel pumps in it now in four years. I have 13.5v to the
pump, steady, but sometimes my internal wiring gets screwy and it'll drop
down to like 9v and then shoot up to 13v. Then I go under the hood and
clean off the terminals and it works fine again - 13.5v steady. It's the
internal power wire that gets corroded. Could this ruin my fuel pumps?
	I could possibly have crap in my tank, and in light of this, I'm
going to put an inline filter between the tank and the pump.
	The third possibility is that not having the fuel pressure
accumulator is ruining my pumps. Would it? I don't have one. I have never
noticed any other disadvantages. Somebody once told me that this could be
a problem, but I haven't heard anybody say they actually know that there's
anything wrong with doing this. I'm loath to get a new fuel pressure
accumulator, because it would mean that I would have to get the two lines
that go to it and from it as well, but I would if that's the thing to do.
	What prompted this is that the other day, my Rabbit started
skipping - it always always runs well up to 7200rpm or so, and it started
skipping above about 5000rpm at full throttle. Sometimes it does it now,
sometimes it doesn't, but it's directly related the the sounds that the
fuel pump is making. When the engine is skipping, so is the fuel pump.
It's going like, bzzzz-bzt!bzzzzzzzt!-bzzz-bzt!bzt! when it's skipping.
	Opinions? Ideas?
	-Josiah
