Some of you installed the Cummins lift pump. I'm about to do it in my truck. I was wondering if I should change the funny clippy thinghy hard hoses for some injection fuel line with screwed clamp. What did you guys did? I never had leaks (air of fuel) and I'm adding a lift pump to increase reliability in conjunction with the Racor 2 microns filter. |

I did a Mr Gasket 7psi diesel only pump. I cut the fuel line with yellow tab right behind the fitting. I also cut the metal fuel line(same line) with a micro sized pipe cut'r and slip'd 3/8 fuel hose over both. one from the plastic line to the new pump inlet, then from the outlet to the metal line. It was pretty much the same install as the Kennedy lift pump install in the tech section but with a different pump. |

oh also, if you do this make sure you slip the new hose over the plastic and metal lines at least 2 1/2 inch to prevent air leaks. also this pump in the gas version is supposed to be a POS, however there are no reviews on the diesel one which i installed. Iv had it on for about 700 miles now with no issue. fingers crossed |

I replaced those funky metal lines with fuel line and clamps. I have the same setup, Racor 245 and in tank lift pump. |

I decided to ad a Sedimentator while I had the tank dropped, so I replaced the hose with regular low pressure diesel hose and clamps. The Sedimentator which I mounted Drivers side just behind the mud flap near the filler hose, traps water and larger debris, thus prolonging the life of the main filter, it is also much easier to drain where I mounted it. It also serves to cool the fuel a little on its way to the engine. The Electrical connector on the Dodge Pump/sender unit, I figured a way around. I took the plug from the inside of the old CRD sending unit and dismantled it and soldered my new fuel pump wires to the connectors and installed these 2 connectors into the existing CRD plug that plugs into the new unit. Worked great and saved about $30 by not haviing to buy a new 4 wire plug! The pump/sending units from any Dodge Ram Diesel 2002-2007 will work, I paid $85 plus $15 shipping on EBAY, mine came from a 2005. Don't forget to take the float assembly from the jeep and put it onto the new unit. |

I left them. I did the cummins/racor combo. Haven't had to prime yet. No problems for 10k. Also, I have never had a dealer bat an eye over the racor or my segr hidden low on the fire wall. I have had it at the dealer twice for documentation on my tc shuddering(trying hard to get a euro under warranty). I suppose I might replace them with short pieces of hose and clamps someday if I get bored. Of course I have a bad habit of fixing things till they break.
