LS1 Swap into 1992 Chevy Pickup

I'm currently helping with the wiring for a LS1 Swap into a 1992 Chevy Pickup. There are multiple ways to wire the LS1 into a 1992 Chevy Pickup. I decided to de-loom the bulk head connector and re-purpose the service wiring (Bat + / Bat - / MIL / Fuel Pump / Ignition On-Start / ALDL) from the old TBI computer to use on the LS1 computer. The TBI system wiring was un-pinned from the TBI computer. The original bulk head mounting plate will be re-installed and resealed. The end goal of the wiring is look factory.

Basically, using a TPI pump to replace the TBI pump. The TPI pump is nearly identical, size wise, to the TBI pump.

I was thinking that or the 96 5.7 Vortec pump. Both fit the hanger with minimal effort.

See pic below for the pump we ordered. It hasn't been installed. About $120, with shipping fees.

Here's what I used

I used the Walbro 255- pleased its quieter than the Carter. Curious where you taking air from, I used a 6.5 diesel filter assembly which takes air from the original location pass fender.

Last week I grabbed a 98 vortec truck's ecu mount, washer res, battery tray to fit on the drivers fender area.

Right now I'm just using the full flow filter - I was thinking about cowl induction but I don't know if I want to spend that much$$$

Any updates..
