hey Grunge,you sound like the kind of person who can fix this problem. Get
under the van and get comfy. Remove the fuel line where it enters the tank.
Then use a coat hanger and ram it inside the tank many times.Or,just go to
the local gas station and use the compressed air to blow in the crud that
has accumulated at the fuel exit in the tank.When the pump cant pull in
enough gas, it will whine. Then if this doesnt work,spend money on a
filter.Too many pumps are replaced with that whine noise that are still
good.Good Luck, Roger Sisler
