Howell EFI conversion

I have a 1990 4.2 wrangler. I was wanting to do a Howell ETI conversion. Do I need I do anything with fuel lines, pump, tank or anything? Or will lines come with kit? I've been trying to research but can't find valuable information.

If you google the kit or look at it on Quadratec, it shows a picture and lists all the parts included in the kit. It includes an inline fuel pump and fuel line.

Since I have the answer, maybe I can save you a phone call. They include everything you need. The kit doesn't run high PSI so you don't need to replace fuel lines. The pump is included and will be plumbed in just before the hard lines start.

The only thing not included is the air cleaner.

When I installed my Howell conversion, I used my original air cleaner. I had to widen the opening on the bottom to fit the GM throttle body, but then the air cleaner was too low and interfered with the throttle linkage. I found a plastic adapter that was from an aftermarket air cleaner to fit a Mopar. That gave me enough height to clear the linkage, and the air cleaner looks like it did when on the carb. I used the same flexible air hose from the core support as well. I did this primarily to prevent any water from splashing up into the air intake.
Another thing that does not come with the kit is an indicator light. This is also known as the check-engine light. You can pick one up at NAPA or Autozone, must be 12 volt. You will need this light if it throws a code.
Everything else is included in the kit, and the instruction sheet is detailed enough for any shade tree mechanic to understand. They also have a tech line phone number to call in case you get stuck.
Here's a tip: when you need to cut wires, clean them first with a little lacquer thinner on a rag to be sure you're cutting the correct color wires.

You will find my write up in the FAQ

I forgot about the check engine light not being included. I wired mine into an existing light in the cluster.
