ls1 question
So as some may know ive been doing an lsx swap in my car. i had to put my project on hold cause of the weather and work and school. But yesterday i had a chance to pull my motor out to see whats wrong with it and after 5 hours i got it back in the car working!
now im gonna start working on the fuel and water plumbing. Any one know what kinda inline fuel pump would work? I saw a summit pump for 130 bucks would that work?
next question is whats a good wireing harness to use? 5.7 or 5.3?

I'm using a Walbro inline with the C5 regulator, works great, not too noisy, I have it all mounted along the rear frame rail using a picture posted in the LS swap sticky. I used the stock fuel line to the front, capped the old return and ran another return from the regulator set up to the tank.
Hope that helps,
Frank

Searh "walbro 255 inline". Here's one with mounts, fittings, etc

You need an ecu that will work with cable vs DBW, which do you have. If you swap over to cable, you'll also need to add an IAC.

Honestly, your best bet would have been to get the engine, computer, harness, sensors, TAC, pedal, etc from the same vehicle.
Some ecus can be programmed to work with cable or DBW, some cant.
And changing a DBW to cable harness is probably not cost effective.
If you use an f body harness/ecu for cable TB and f body injectors, you'll also need to add an IAC and change your MAF and IAT sensors.
At this stage, I would suggest buying an aftermarket harness and ecu from the same source. Have them set it up for what you'll need in terms of sensors, etc.
