Some pumps whine more than others. I would pull the feed line off that
goes into the pump and make sure the gas flows freely out of that line.
Keep replacing the inlet filters regularly. There may have been some junk
in your new tank. Check the fuel pressure back at the engine. It can tell
you if the regulator is working properly and if you have some kind of
pluggage. Rev the engine and hold it for a few minutes and see if the
pressure remains constant. If it starts to drop off, you have a plug
somewhere.

Sorry I was unlcear,
afer the new to me used pump started to whine, I replaced it whith a brand
new one, which is still whining. If it is a vacuum problem, how long
should
I have to run the van with the fuel filler cap off? I just tried that, let
it run for a minute or so and the pump was still whining, will it take
longer
than that?
Greg.
