On a '91 Blazer Motor I'm trying to figure out which line going into the Throttle Body is the pressure side and which is the return. Both lines run in on the back side of the throttle body, and there is one the passenger side and one on the drivers side.

This motor is going into a Jeep so the original fuel lines have been cut and I'm not sure which is which....:rolleyes:


Thanks,

Jeremy

The feed line is the larger of the two. It's on the driver's side of the TBI unit.

Glad to hear it all came together. Is it in a Wrangler or a Cherokee? Did it have a 4.0, 2.8 or a 2.5?

u picked a good motor to throw in a jeep :) ive seen a lot of 350s and 302s but not many 4.3 swaps. seems like it would be more common for jeeps cuz theyre a few hundo pounds lighter than a small block

It originally had a 4-cylinder, 5-speed combo in it. It's a '92 Wrangler. Now it has a 4.3, 700R4, and NP231 from the Blazer and I used a Painless wiring harness and Advanced Adapters Bolt-in Chevy v-8 engine cradle to put it all in...

I have some details at http://www.jeepinrocks.com/

Now to put the conversion radiator in and finish off some other stuff so that I can leave it running for a while and start working out the bugs and get the rest of the drivetrain together...
