What year is your donor mustang? One other code you will have besides speed senser will be evap press senser. Not a big deal, nothing that will efect performance.

ok the EFI motor i got this weekend is a 1990 5.0 HO. from a mustang. I plan to use a RCI 19gal fuel cell in the bed. Any thoughts on running a intank fuel pump?? I'd really prefer not to run all the other pumps/accumalter,etc. I've been looking and dont see a nice drop unit for the RCI, but is there a way to add one?? Thanks,Chuck

Probably not, my suggestion is to use a frame mounted pusher pump(at the tank) and then the high psi pump closer to the motor. A great aplication for a high psi pump is the F250 pump from late 80s or early 90s. The pusher(or primmer) pumps I always got an off the shelf unit from napa.
To bad you didnt take my book afterall, I had the 90 mustang wiring info right in there. I'll scan everything and get it to you.

haha...pad that junk on your own time...hehe.

ok, i have been on the phone with Aeromotive,Jegs, and RCI...im not getting much help on this. Aero suggested i build a duplicate of their steel sump to weld into my Alum tank. Im worried about that. I just find it hard to believe i need to run 2 pumps...what about a holley blue or black...surely that can work by itself???

Robert, what are you using in your efi swap?

I remember holly making one that was strong enough to suck out of the tank and creat the correct psi. But it was spendy ($300?).
The f250 pump is cheap, a pusher mounted by the tank usualy around $30.

What does the mustang run? I know they only used one in tank pump right?

I will see if I can get some wiring diagrams before this weekend.
