I should have mentioned that if you find that the fuel pressure DOES 
drop under load, then you will also need to check the voltage at the 
output side of the fuel pump relay, also while the problem is 
present. The relay contacts sometimes get resistive, and this can 
reduce the pump output even when the filters are fine.
