<<Suction screen in fuel tank is getting blocked with crud.>>

True -but not always. I put a new tank in last year and my pump is noisy
again.
Just 2 days ago in Idaho I could'nt get past 40 mph.

My engine began to lose power and stall as the noise increased . I reversed
polarity of the pump momentarily and turned the key a few times.

After reconnecting the wires correctly it started right up.
I got all the power back and the noise went away.

I suspect the pump brushes are worn. Since every pump I have as spares makes
noise,so  it's finally time for me to get a new pump.

I took an old pump apart once and the commutator was deeply grooved from
wear.
Reversing the pump apparantely helps the brushed make better contact?

Suction screen in fuel tank is getting blocked with crud. Time for a new
tank. This is becoming a frequent problem in these vans, especially so
called low mileage ones that have spent periods of time unused. So far,
the best source of tanks so far has been Bus Depot.

The fuel pump on B. Bones was excessively noisy, so I robbed the almost
silent fuel pump off of Long John.  HOwever, that same quiet fuel pump
is also very noisy on B. Bones.  What gives?  How can it be silent on
one bus and so noisy on another?  Mounting brackets are the same,
connections seem the same ...

What gives?
