piston lift pump came apart

[dunes450r]

so i'm just getting around to rounding up parts to install a hvlp lift pump that i got used from a member on here. figured i'd open the pump up real quick before installing it just to make sure everything is good to go inside. and here is what i found:



i'm sure the seller had no idea it was like this since he had ran it with no issues before pulling it off in favor of something else. i've sent him a message to discuss options but i'm curious what everyone's opinion is on what can be done with pump. is it salvageable? what should i do?










what kind of lift pump screen or prefilter are ya guys running to keep junk out of your piston lp?

is this too simple?

[cmann250]

Yea that'd work. I'd bet you could find one even cheaper at the local lawn mower shop.

I've seen guys use this too http://www.genosgarage.com/FLEETGUARD-U ... fo/FF5079/

anyone? appears the parts that got chewed up are the diaphragm/one way valve that lets fuel travel from the inlet side to the pressure side of the piston?

Just buy a lpplp kit from rccummins

[RCCUMMINS89]

Over on Cummins Forum, there is currently a used low pressure piston lift pump kit for sale for $150.00

It's not one of my kits, so I don't know if it's a DAP kit or a Cummins lift pump. If that's a Cummins pump, that's a steal.

Is there issues w/ the dap pumps?

[RCCUMMINS89]

An issue? No, but they are not a whole lot better than a stock diaphragm style. They seem to push anywhere from 5-9 psi (sometimes a bit more), and aren't near the quality or move the fuel that the Cummins low pressure pump does.
There is a reason that you can buy the DAP pump, directly from Oregon Fuel Injection for $78.00

That inlet screen catches only the really big stuff, what I have used before is a in line strainer, Fleetguard FF5079. It will keep out the junk that gets pulled up from the tank. Without a capable strainer, the screen can plug, and/or the piston walls will get scored, hindering output...

BTDT.

i wish that was the problem, the diaphragm is trashed, as in it came apart and the previous owner kept running it without knowing, then sold it to me....

Just a related question, how often should one change that pre filter?
