Engine/Transmission (1998.5 - 2002) lift pump or pusher pump

[jglasgow]

I met a guy today with a 1999 CTD, He asked me if his lift pump was going south, do you just replace the lift pump or do you get a pusher pump and do away with the lift pump completely. I told him I didn't know but I knew some guys that probably did. I tried to do a search but things are running kinda slow since the big change over. Any help would be much appreciated. Thanks from a third generation guy!! -John

I guess the easy answere is to just replace the exisiting lift pump. Adding a pusher is probably a better solution... but more of a project than simply replacing one.

If his truck is stock I would just change out to a new pump. Tell him not to buy from the dealer... . double the price, but rather from Cummins PN 3990105. Price should be ~$150. 00. This pump has been around since ~5-01, and for the most part has been pretty reliable. If he's heavily bombed, I would consider a pusher. Lots of archive info on choices, etc.

I just met this guy and he has bought a bullydog fueling box and a few other things. I told him he needed gauges, starting with fuel pressure and egt. He already had an AfE intake system on the truck and I think it had about 120000 miles on it. I told him he needed to join the TDR web site and gave him the sign up sheet, so I think I've got him off to a good start. Thanks for the additional info on the pump.

I did away with my stock pump completely... installed a Black Holley on the frame back by the tank... GREAT improvement.

Truckstom, What kind of pressures do you see? I just switched from a Carter 4600 pusher and stock lift pump to a Carter 4601 alone. I see 11-12psi at idle and 6 or so at WOT. A little lower than I hoped. I'll try it a while and see. With the pusher pump setup I had 22-28psi at idle and never lower than 14 psi.

Just move your lift pump back to the tank. 17lb at idel, 12 WOT. caa,t beat it . 1/2 Wildcats lines. H Anderson

For a permanent fix of this most vexing problem the following link explains what you can do. After this modification you can basically forget about fuel system problems.

Turboman,

At idle it's 15psi... at 70 mph w/ comp on 3x5 it's at 12... WOT it's at 10 psi.

even the stock carter works better if you put back by the tank. IMO.

Dcochran... . I looked at the site u had linked and it looks like a very promising system... . Unfortunantly though the page with the price for system was under construction at this time... I was wondering how much these kits usually run... Any info would be greatly appreciated... Ty
