The carb we will be puting on is off a old 81 Chev truck we have here.
The spec for fuel pressure is 7.5 to 9psi as listed below. The spec for the fuel injected 93 is 9 to 13 as listed below.

A person on the other end of town did it with no problem so I figure it will work for me.
I just cant get a hold of the guy right now.

I think the fuel pressure difference can be handled by the inlet needle. We will see.

We are getting another truck in the new year and its more or less just a yard truck right now.

The darn thing keeps acting up and I am getting tired of replacing parts just to have it go bad again in 2 to 3 days. Its actually my dads truck so I have to go there to get it going again.
So I figure to experiment with the TBI to carb changeover to make a quick gauranteed fix once and for all till we replace the truck in a couple months.
