I have noticed that my high pressure fuel pump(FI) has been slow to come up to pressure(gauge in rear window). The other day after sitting for 6 days it would not come on at all. Then later that day it came up but was slow. Now I notice that it doesn't seem to run as fast as it did. It gets the pressure up but sounds a little slow. Is it about to give up the ghost, or does it sound like it has picked up some trash in the line. About a year ago a piece of the AN fuel line to the pump lodged in the pump and stopped it cold, but has performed well since til now. This pump is an external Aero unit and it is not easy to get to. Suggestions?? What is the average life expectancy of these type pumps.
