In-tank lift pump: How many miles with it....

Hi all,
Just because i am curious (...and also very hesitant to go for the mod :wink:

)

Can you post :
1) What was the mileage of your KJ when you made the Mod ?
2) How many miles you have made since then ?

Thanks !

Around 130k, my original fuel filter head was finally leaking horribly, so I picked up a new filter head and a lift pump, I figured I would kill two birds with one stone.

Jeep has around 146k now.

I put mine in at about 68000 have about 3k on it. I did the cummins type in-tank lift pump, Install was not difficult just took a little time. Jeep seems to run and start smoother with the lift pump and I like the idea that it primes the fuel system every time I start the Jeep. I only had a few times where I had to manually prime it before the lift pump but I have not had to do it since.

This is the pump I used, Less than 130 shipped. Fuel level arm swaps in about 60 seconds, trim the index tab and it drops right in. There is plenty of write ups on here on how to do the wiring, I chose to make my own harness. But its really as simple as tapping into the right power wire and adding a ground. I basically used female connectors from auto zone and then filled the plug on the fuel pump with electric safe safe sealant (Blue gasket stuff) to seal everything and ensure the wiring doesn't/can't come undone.

Installed around 30K. Have about 120K now. Used factory Dodge back when you could still get them. If you plan owning for a long time, the joints will eventually leak under vaccuum. Intank is the best way to go, in my opinion.

Interesting, the most mileage run with a lift pump is 90 kmiles. Looks like that the extra pressure doesn't create any problems long term.
Also interesting to see that not many people have a lift pump installed....
Thanks guys !

Put Dodge in-tank in mine at 28K, now at 104k. Running CAT filter with no issues....knock on wood.

Installed the in-tank pump from the Dodge RAM diesel (Cummins) pickup in mine @ around 30k, now at 165k. Running well, strong, etc. It cured all the air-in-fuel, hesitation, smoking stuff. Installed the SEGR too - I think those are the two most important upgrade/fixes you can make - and between them the CRD has been the gem it was supposed to be.

Seems that 135 kmile is the max that has been driven with the pump.
Really interesting.
