Mopar MPFI fuel line question on 85 CJ

Hey Everyone. I am knee deep in my frame swap and the more I take apart the more I see needs to be replaced. I was pulling the original fuel lines out and they dont appear to be in great shape so I figured i should just replace them.

Question 1) the prebent lines are $99 at 4WD and there are three (I think). Is there another option?

Question 2) I have the Mopar kit installed and I know they changed some of the fuel lines. Does anyone else have the Mopar kit and know where I can get those lines? I installed it over 10 years ago.. and I forgot what it involved.. so I guess question 3 is.. if I have to get the prebent lines... and I wasting money if I have to cut them... is it hard to bend fuel line?


Any pics or diagrams would be great

Just get a tubing bender, a tubing cutter and follow the stock line bending. Did that a few month ago with the tub on, not a pleasant job but with the tub off it's should be easy. the bending part was fan, installing it wasn't.

Run 3/8 line from the fuel tank to the fuel rail and 5/16 for the return line. both on the driver side.

Agree with COAS, cheaper and easier to bend yourself. If you really want to buy prebent try HESCO. They make (and install) the MPI kits. Hope that helps.
