it is an SM-465 and a NP-241 with a shorty SYE and it is actually shorter then the stock set up. i installed the engine about 4" forward of the original 2.5 mounts.

put it in the tank, but dont mount the tank back up and try it against your fuel system to see if it builds psi?

That's what I decided to do. Now the pump that's in the tank is a bosch is that normal? Also I worried about hose clamp fittings with 62+ psi I wonder if it's going to leak?

Got some more work done today. got the pull type slave cylinder for the clutch had to fab a bracket for it but its all installed. also started to clean up the Ford 8.8 to install it tomorrow. I decided to do this swap at the same time because I have to have a drive shaft maid. I'm using a CV style out of an XJ so why not.. I also dropped the fuel tank to adapt the Pump.

OK so I'm faced with an dilemma what fuel pump to use? Ive done allot of research and I'm getting conflicting reports. some say if you have a 92 or so 2.5L MPI the pump will work and deliver the said 62 psi. now there reports that say different. now the other obstacle to cross is fuel lines. I don't want to rely on hose clamp fitting with 62 psi in them what has anyone done here? I thought about going down to the you pull and see if i can grab some lines out of a blazer or van and maybe scoring the pump as well..

Any thoughts???

I've used braided line with AN fitings for turbo applications before, just an idea if you want to spend the $$$ for it.

i used SS pex water line crimps inside my fuel tank, and used a fuel pump from a 3500 pickup. the stock pump wont deliver what you need. ask me how i know. i just swapped the pumps in the tank and been great ever since.

Lol I keep getting conflicting reports on that. I got a pump from jk it's out of an 96 with a 4.3 but I'm sceptical on it too so I'm going to leave the tank down till I try to fire it up and see what works .. Lol got the Ford 8.8 installed ..

fuel pump

By the way, I used the stock 95 YJ in tank pump to supply my 92 4.3 TBI. The YJ had the 4 cyl with factory fuel injection. I just adapted the fuel lines to the tubes that are attached to the TBI unit. It has worked for 14 months with no issues. The 92 TBI unit has a built in pressure regulator and returns excess fuel to the tank via original jeep return line.

I got the slave cylinder from here.I figured it was the best option with the set up I have. well I got some Dorman 800151 and 800153 fittings from Napa they have the GM fittings on one end and a union on the other. as far as the pump Im not sure yet. I might go to the you pull tomorrow and see if I could score a pump out of something..
