thank you i have looked at this but i saw how the maf hooked up thanks to yall for the wire diagram but still what about a stock fuel pump off my stock 1990 will it work or is it absolutely necessary just to run the car to upgrade it or is ok stock and yes i did read that before i posted

To be honest with you man Im not 100% sure. I think it will be lean up top?

The car will start and run yes, I see no reason it would not. Correct me If Im wrong someone.

I ran my stock fuel pump for 8 months with my CA. the walbro is a great upgrade though.

IIRC the stock fuel pump isnt great when you upgrade beyond the stock 370s...... but I had no problem at all with my 370s and the stock FP.

The stock fuel pump should be fine as long as you don't turn up the boost.

DO NOT plan on dropping this thing in the car in a weekend and driving it to work on Monday. You'll be sorely disappointed. You need to plan on having another vehicle for at least a week, probably more.

It's not that it can't be done. It's that it probably won't be done if you've never done it before.
