HP/TQ gains?

1. How will i get the new fuel lines to adapt to the Renix lines? I got the lines full length all the way down to the frame rail. Flanger?

The '94 injector rail and fuel lines that you have should be plug n' play.

Unfortunatly this is incorrect. The 91+ lines have smaller pieces that go from the fuel rail to the hard lines along the frame rail. In the RENIX era, the fuel lines are all one piece from the fuel tank, along the frame rail, all the way to the fuel rail. The problem with the RENIX lines is that they are too short to reach the input/output spots on the rail. These are both towards the front of the engine on the 91+. The Renix has one up front and one towards the back.

When i did mine, i just got the hard fuel lines that went along the frame rail and replaced my renix lines with them (i got them from a junk yard). These lines allow you to connect the other shorter lines that come with the 91+ era. Other people tend to just leave the RENIX lines and adapt them in some fashion. This tends to involve cutting and minor fabrication \ adaptation. Im sure it can be figured out fairly easily... but i opted with the OEM route which only makes since.

Now knowing the problem with the fuel lines, why cant i just keep the old Renix rail AND lines.

and about the PS pump, i will have no problem getting the 97 model, BUT will that bolt up to the rest of the older system/brackets???

and what about the PS lines that go to and from the steering box?? Will the fittings swap over?

Thanks for the correction, and I'm glad you found a solution for that problem.

The old RENIX rail will not fit on the intake manifolds 91+ without fabrication (Holes dont line up). The 91+ rail and FPR are also better IMO.

I used the later model PS pump and all my lines fit just fine.. no problems there.

Thats good to know for the fuel setup, BUT for the PS res it all depends on what it is going on. I have a 1990 comanche. What about you?

If you get a '97+ XJ PS pump with mounting bracket, it'll mount directly to the '99+ intake manifold. My PS pump/bracket and intake manifold came from the same junkyard '01 XJ so I was lucky. All my other existing '92 bits just bolted straight on, and the only other things I needed to do to make it all work was to adapt a couple of vacuum lines and extend the wires to the IAT sensor. It was pretty easy really.

[ftpiercecracker1]

Ok, well according to your signature, you (cheromaniac) have a 92 xj, which means its an HO, i think. My Comanche is a NON HO. I am unsure if there is a difference between the two as far as PS setups go, but before i go to the extra expense of buying another PS res i would like to see if there is anything i can do to make my original PS setup work, i am pretty good at fabrication and have a handy little mig box so i may be able to do without.

What is the IAT sensor?

[Cheromaniac]

What is the IAT sensor?

IAT = Intake Air Temperature

90 Cherokee.

I purchased a 99+ PS Pump and brackets to go with my 99+ Intake Manifold. My RENIX PS lines mated to the 99+ PS Pump just fine.

If you want to use your RENIX PS pump you will have to use a 91-98 Intake Manifold (unless you do some serious fab.. check NAXJA maybe for details?) which would be silly. Sell your pump and buy a 99+ with bracket and idler. (got mine on ebay).

[ftpiercecracker1]

Thanks bud that was the info i needed. Knowing that everything WILL bolt up it would be pretty silly to stay with the Renix PS, especially for the price i can get it for.

thanks

ok so heres the NEXT list for my next trip. . .

97 ps Any jeep inline? Other Years?
99+ intake man
91-95HO hard fuel lines

Did i miss anything? let me know if there are any other Problem areas as this is my first time building a stroker.

thanks again
