Fuel pump replacement (in tank)

[PilotHouse2500]

Looking for a good replacment for the in tank fuel pump for a 94 2500 12 valve fuel system.  Old one says Carter, but Summit images don't look similar.  Any help on a good quality replacement brand and model number?

Might be challenging. 12V engines as far as I know never had a in tank fuel pump. This had to be retrofit deal.

My 92 that I had for 23 years never had an in tank pump, ran off the cam,  mounted on the side of the block. Later on I changed the original mechanical pump, lasted 250 k, so I thought it time to change. Never had the newer version go more than 100k miles. When comparing new to old, bought from Cummins, the newer was built cheaply. I would go for one on the frame with a prefilter.

curious.....I'll take pics today afte work to post and see what's going on from the mind here....maybe I'm mistaken in the "what" of what was in the tank (it's broken).

I’m not super well versed, but all the 12 valves I have seen, trucks and industrial, were mechanical pumps that ran off the cam, like @JAG1said, with the hand primer.

12V typically have a fuel basket with pick up tube and fuel sender for the gauge.

This is the thing.  What would I look for on Summit?  And if there is a "best" brand?  Yah not a fuel pump nnow that I look at it....

to answer my opwn question, I believe this is the critter (thanks for the hints as the "what")?

Only you don't want those screens in the bottom if they are there.  Remove those and provide a nice water separating prefilter before the lift pump then a high micron factory filter before the injection pump. In my opinion the 12 valve high micron factory filters under near the intake are way too dinky.

 

Forgive me if I am repeating what you probably already know... need emoticon that has the whole crowd rolling their eyes at me.

Thanks...now I have to remember that!    Fuel system plumbing will be next summer/fall likley.

Forgot to say that it's good to have shut off ball valves on the fuel line before and after the prefilter. I helps prevent priming loss, fuel drain back. Also use them to shut off fuel in bad neighborhoods to prevent theft. I think there may be a way to put a lock on any of the two shut off valves. Haven't figured how. Mike knows a good way for security. I wouldn't want a truck like yours to get taken since it is an eye catcher.

yah I was planning on some ball valves...I have several things going for me for anti theft...its a manual, and its starting method will be...non standard!
