P30 Fuel Pump Service Life?

you can always do some careful measurements as to where the fuel pump(s) are located from the outside, and transfer them to the inside, may get lucky that the pump not be under the hot water tank or something like that, worse part is when you have just filled the tank and a few miles down the road it fails. Over the years i have had to drop many full tanks, not too bad if you have a transmission jack though, would rather drop one almost empty though.. but that does not happen often.. Just remember some had a prefilter (sock) over the end , always replace that, and check the lines on the top of the sending unit if there are steel, have had to rebuild a few sending units replacing the lines, and brazing in new lines.. Outside of the tank of course..
