James,

You might have something clogging the screen in
the tank which restricts the flow.

I replaced my tank, and last fall on a road trip,
I spent the day under an Oregon bridge in a
rainstorm trying to figure out why the engine
wasn't getting gas.

I reversed the leads to the pump and backflushed
the pump (with the filter removed).

This got me going again.
When I got home, I removed the tank and rinsed it
out and it has a leaves, string, plastic
wrappers- that was all from a gas station in
Bakersfield.

When the pump is known to be good, and then it
gets noisy, that can be fuel starvation.

If you backflush the pump, make sure the filter
is off, or, backflush with the filter on into a
bowl to see what's in your filter.

I can only wonder how all that garbage got into
the gas in the first place.
