The way OEM's do it (and I did it) is like this Trans out>radiator>bottom of B&M cooler>top of cooler back to trans. You want to run it to the bottom of the cooler first to eliminate air bubbles. There is a ton of pressure coming out of the trans so no worries there. Also run your aux cooler with the fittings facing sideways to eliminate air bubbles as well. You want to go to the radiator first because it takes a massive amount of heat away before the air cooler get's to it. Water cooling is far more efficient.

Thanks Bro Montana! I did set up my aux cooler vertically but I wasnt even thinking of air bubbles, just ease of routing the lines. I wasnt sure if it would make a difference pushing the fluid uphill through the cooler/radiator but I guess it has to go uphill either way. Are air bubbles an issue? wouldnt they just get pushed out of the breather/vent?

air pockets can be an issue if you run it with the fittings down. thats why, like clint said you run the coolers with fittings 'up' or more commonly 'to the sides.' and yeah in a properly set up system, air will be pushed out of the lines.

summit racing man... fittings and what nots within a day or so. theres a warehouse in sparks nevada... i guess im spoiled. my summit orders show the next day if i order by 8pm.

looks like the 90*s you got will work fine. again make sure you seal them. im a big fan of quality liquid teflon. works awesome.

They do ship my stuff out of Nevada but it still takes 3 days to be delivered once I order it. Rural dude...

I set up my aux cooler with the fittings on the side, and I used Teflon thread tape on all of the threads on the radiator. My fuel line should be in today so I hope to get that all hooked up and get the fuel tank back up. I'm guessing that my new harness/pcm/fuse block will have a spot for a fuel pump relay? I guess I will just run a power wire from my weather pack and let it hang out until I know where its gonna go. I'm getting anxious about my harness. This last Monday made it 3 weeks since it was delivered to him...

I stopped by this afternoon and screwed with my transmission lines. I cut, flared and bent them so I can hook up the rubber hose right at the frame. My 3/8 fuel line and bender came in so ill be hooking up fuel tonight.

Also it appears that the Jeep side pigtail for the fuel wiring has the correct female already, and 3 wires. Anybody know off the top of their head what is what? Maybe I already have a fuel pump power wire I just dont know where it ends up.

my guess... 10 to 1 for the 3 wires... power to fuel pump, ground to assembly [which provides ground to fuel pump and fuel level sending unit] and fuel level signal return, but idk for sure. id chase the wires and verify where they go or check a factory diagram. might have an open port for a fuel pump relay in the fuse box? i would say for sure that [1] is sender signal and [1] is sender ground. the [3rd] wire might just be a wire that was run when jeep knew the efi was coming and changed harnesses in production.

needless to say id still chase it. then id use it once you figured out where it does or doesn't go.

Thats what I was thinking, fuel pump power, ground and fuel level signal. I already shipped my old sending unit to you so I can't cross reference it! Its gonna be hard to trace because it goes straight up into a loom under the tub in the back. I'm guessing that they set all of them up this way because of the fuel injected 4 cyls. When you get the sending unit on friday will you let me know what color comes from the fuel level?

I got all of my trans hoses ran just like Clint said to, but as I was putting on the last hose clamp they are pretty close to where the pass. side manifold dumps. Hopefully they wont be in the way. I didn't get to working on any of the fuel system. My friend with an 87 yj bought my old exhaust so I helped him install that. It's amazing how things can be just slightly different. This exhaust was built and installed last fall and fit mine like a glove, but it was a PITA to get everything lined up on his.

Does anybody have a good resource for wiring diagrams? I don't even check my Haynes manual anymore, they never tell me what I need to know.

No problem. Very handy site, plus they have good OEM parts diagrams.

I couldn't find what I needed on there. I have to go check a job so I'll do some more digging when I get back

This sounds redneck but could I just run a wire from my battery until I find the one that kicks on the pump?

Why don't you just pull the fuel pump assembly out and look at it? I don't think you want to be sending voltage to the wrong thing in a container full of gas.
