It's when the pump is load it can not always get the power it needs due to old wiring, I am not sure if this weak point applies to ERST but it is a weak point on Cosworths!
It of course might be something unrelated.

Pump (uprated bosch) & filter(genuine) has done a 1000 miles, then went for a set up on the rollers.
The car was going lean on top end thats when they checked the pump
but all was good. I think there may be crap in the system, i was just going to
replace the pump & filter again thats when i came across those pre fuel pump
filters but dont know if there any good/work.
