im thinking of swaping to 90-92 SD TPI and have read the tech papers a few times and looked over my manuals..i have a few questions... i know ill have to change the fuel pump. but what about the fuel lines that are in the car? also what kind of fuel pump should i get?? im looking to run 12's. so what pump should i get?? also is there any diffrence in the 90,91 and 92 harness??
thanks for the help,
RS

 

about the fuel lines?that depends on who you talk to?if you plan on producing a good amount of horsepower you need to upgrade your fuel lines.the TBI fuel lines are smaller than the TPI.i'm going with a -6 braided line for my swap(305TBI to 350TPI).ACCEL has a a set of fittings that screw into your hard lines coming off your fuel rails to except -AN fittings.
wiring harness?as long it's SD and TPI they'll work

i was just up in cincy last week. ill be up in june ill have to look you up.

the "hard" lines are smaller..the one that come off the pump and return to the tank..or just the soft part on the drivers side to the hard lines going to the TB.

thankx,
