'94 2.5L Fuel Pressure Specs

Hi guys,

 

Current rig:  '87 2.5L 2WD, AX4, Renix

 

Looking to swap to '94 2.5L

 

The current engine leaks oil like the exxon valdez.  I bought a newer 2.5L which the PO indicated was from a '94 YJ (but I did not verify).  I am prepping for the swap and one question is the fuel needs.  The new engine has port fuel injection whereas my Renix has the TB. My plan is to swap in the new ECU and accessories from the '94 and ditching the Renix.

 

Will I need to swap the fuel pump and/or pressure regulator?  If yes, are there other components in the fuel system which need swapping due to the higher pressure (filter, lines, etc).

You would need to swap every bit of wiring in the truck.... and everything else from a 91+ 2.5 XJ/MJ.  Just bolt your TBI system to the new motor, and you should be golden.

 

You may need to swap some sensors over from your old motor.

Thanks for the confirmation.  I came to the same realization after researching more.  I will strip down the  '94 and bolt it up to the Renix.  I will tackle the wiring another day.

Thanks Cruiser!  I wouldnt have thought of that....  My '94 came with the AX-5 4X4 tranny and was just going to bolt to my AX-4 no questions asked.  Saved me a massive headache!
