Engine/Transmission (1998.5 - 2002) Unusual lift pump situation

[MoparMark]

I purchased my truck used and somewhere along the way the lift pump

has been replaced with an automotive

electric fuel pump. I installed a fuel pressure gauge to the fuel filter housing, 1/8" pipe thread. I bumped the switch and only had 7psi When I started the truck I had 0psi I hope the injector pump is not trash now. My problem is, after looking at the replacement pump from the local Cummins dealer, that I'm missing the connection from the factory fuel line to the lift pump banjo on the inlet side and the other fitting, banjo or other???, from the pump outlet to the fuel filter. Are these going to be dealer items?



Thanks

Fuel lines

Since it's gone anyway why not go with A-N fittings and 3/8th hose.

E, what are A-N fittings and were can I get them. I have the new lift pump

3990105 $127 and harness 4025182 $6. 56. Do you or anyone else know what the threads are on the pump inlet and outlet?



Thanks

Any speed shop should have the pieces. Summit racing is the cheapest. You need a adapter from Earls it's a 12X1. 5mm for a carbartor. Then it's -6 fittings the rest of the way. Over at www.nwbomber we posted all the parts needed from the tank to injection pump.
