87 Plymouth Sundance 2.2 135k miles
This thing was stalling out on the road, here is the first look at the fuel pump pattern.
As the engine would begin to get a bit ragged and ready to die, the pattern got worse.
Here is the pattern just before the engine stalled, the pump is giving up.
This is what came out of the tank, looks very expensive. Customer opted for aftermarket pump.
Here is the problem with this one, the commutator is completely worn out.
The brushes are at the end of their rope. (no pun intended)
New pump pattern.
