Your new to this whole internet forum posting thing aren't you?

Is there any difference between the Kennedy and the Delphi lift pumps? And (forgive me if this is a dim question) what is the advantage to fitting a lift pump? Does it replace the oem fuel pump?

There's only one REAL way to add a lift pump :shock:

That's to put it into the tank :wink:

Everything else still has to suck a vacuum through the fittings by the tank.

If you plan ahead and let the tank get low it's not hard at all to drop it and put in a Dodge/Cummins lift pump :lol:

That is if you don't have a skid plate on the tank :roll:

You'll need to switch the coat hanger arm with the float on it so the guage reads correct and trim away part of the locating tab on the pump so you can orintate it correctly.

I chose the in-line pump for a reason...

I wanted a pump I can by-pass in the field if it fails (limping home with a failed pump is not an option for me), with the inline I simply pop off two line sand put the feed line on. Yes in tank pumps are flow through (or you are crazy for putting them on), but they still flow much more difficult than a system without one, which you are worried about (or you wouldn't be adding a lift pump). In-line lift pumps are designed to "suck" fuel... I personally wanted the plastic quick connect fuel lines out, so I am no longer worried about sucking air through them.

Post subject:	Delphi Lift Pump Installed
I just finished my temporary install on a Delphi Lift Pump... Temporary because tomorrow I will drop the tank and do away with the plastic fuel line, and extended my fuel tank breather. Delphi pump is an inline pump that puts out 1-2psi, with 35 gal/hr flow rate purchased from Diesel Care & Performance. Driving is excellent, and I am very happy to get rid of the air leaks... I also needed this done before I send out ECU to GDE, so I can distinguish what changes were from what...

I may want to install one as I really don't want to drop my tank. Dave

Pictures are coming, very easy to install minus replacing the plastic fuel line. Only way I see to do that is drop the tank, but will be worth it. The other posts on this matter are spot on for finding proper wire, etc. Pump works great...I was obviously having more air than I realized as engine is completely different especially at start and idle.

Post subject:	Not that new, just old and cranky
Noob, maybe...I just don't like the BS. I use this sight as a great tool, I am way to busy in getting this Jeep ready to ship for childs play... I certainly owe pics to all those others out there who have done such great write-ups, so they will be here shortly. I guess I'm just getting cranky in my old age, because I used to have a sense of humor

AltE...seeing how I intend to install a lift pump in the near future...how do you know which fuel line from the tank is the supply line. I figure my luck, I'd install it in the return line, and that wouldn't solve much. Is it marked explicitly? While I've been under to poke around, I haven't identified with certainty the supply line. I haven't been able to identify it from pics of others installs. Thanks.

The large fuel line is the supply line, it is very clear...

Look at the plastic lines coming out of the tank, is much more clear which is bigger. It is a little hard to eyeball the metal lines, but the plastic line if significantly larger when you are laying under the vehicle.

Thanks. I'll be a little more confident that I'm not cutting into the wrong one. I had traced the metal lines back, but hadn't paid a lot of attention to the plastic ones. Mine is currently suffering from the hesitation and there quite a bit of air gathering in the fuel head...no leak in the heater connection, but I do see a little seepage where the puck and head join. Thanks again for the guidance.

Does it replace the oem fuel pump? Chrysler forgot to install our lift pumps. I ordered the Cummins in-tank version last week along with the connectors that go to the existing wiring. There are a couple of threads about it in the tech section.

Yeah, your right Joe, doing the intank pump would be the best way to go, may have to put it off a bit...every day for the last 2 weeks has been over 100F in the shade DAve

Post subject:	Inline versus in tank
I chose the in-line pump for a reason... I wanted a pump I can by-pass in the field if it fails (limping home with a failed pump is not an option for me), with the inline I simply pop off two line sand put the feed line on. Yes in tank pumps are flow through (or you are crazy for putting them on), but they still flow much more difficult than a system without one, which you are worried about (or you wouldn't be adding a lift pump). In-line lift pumps are designed to "suck" fuel... I personally wanted the plastic quick connect fuel lines out, so I am no longer worried about sucking air through them.

If I were you I'd worry about sucking too.
