[s-cars] Ideas?

[Tom Green]

I agree, Bob.  Acts like a fuel starvation problem, like the fuel pump
has failed.  You might check the output from the pump in a container
at the filter.  My guess is you won't need a very big container.  If the
pump output is good, I would look for water in the filter before blaming
the FPR, even though the half tank of fuel makes this unlikely.

Tom, firing on all five with POS change.
