Attention: TDR Forum Junkies Well I have been watching my fuel pressure. I never knew what it should have been only had the gauges for about 6 weeks.
I had 10 psi at idle and 8 psi at 70 mph
no load.
On ocassion the pressure would drop to 6 psi on the highway
This weekend I installed a Product Engineering PE4100 fuel pump. I also installed thier PE1050 dual relay wiring harness.
I cut the fule line near the tank and used a tubing sleeve and tubing nut to convert to braided stainless steel fuel line. Now I have the BSS line to the pump, from the pump to the filter and from the filter to the injector pump.
I never liked banjo fittings they just seem like they would cause a restriction, fuel changing directions to many times. Also the stock fuel line from the filter to the injector pump looked alfully small. Biggers better right?
I wired the relays to the stock lift pump wire so the new pump will run under the same restraints as the stock unit.
Fired it up and oh boy
15 psi at idle, 14 psi at 70 mph. Empty I haven't gotten the psi to drop below 12 psi. When I first started it up the psi was a little lower but after about a 10 mile test drive the pressure was up.
I scanned some pictures in but I will need some advice on how to post them.
