FUEL FILTER HSG SEALS

Substitute: Get 1/4 NPT to 3/8 hose barb nipples and totally remove the hard lines. The inlet line down to the fuel(transfer) pump can be cut a couple of inches from the pump using a tubing cutter, and the 3/8 hose slid over it and clamped in place.
On the output side, you could either do the same thing a couple of inches from the IP, or buy a couple of adapters and eliminate the entire hard line. I did the latter and used these parts:

I was able to use this setup quite nicely, and as an added benefit, with a slight bit of sanding on the back corners of the brass parts I have been able to remove the IP /with the fuel line connected/(without removing the IP gear). A *lot* less mess if you do that sort of thing.

Insert it inline before the fuel filter, after the transfer pump.
It does two things:
1. if you run out of fuel, you can re-prime the system before wasting your battery cranking.
2. It acts as a check valve, preventing fuel drain-back if there are any leaks in the system. Really helps with starts if the truck has been sitting for a while.

I know that the better ones are less likely to do this, but the cheap "mr gasket" style pumps are very prone to this. And the IP won't generally suck through the electrics.

I have an e-pump,it's a great mod. Mine is solo, i.e. the lift pump does not function,and is bypassed as the e-pump will fill the crankcase if the diaphragm in the lift pump fails.
