Depending if you want to get more HP out of your TBI engine you may want to go with a Vortec Pump, it is an exact cross over and fits perfectly. Just gives you 155L/Hr instead of the anemic TBI pump. Make sure you change the fuel filter, suction strainer, and clean the ground contacts as well. With this pump I've run as high as 28PSI with 61LB/Hr injectors and as low as 15PSI with 80LB/Hr 7.4L injectors, IMO it'll run at OE pressure ~11-13PSI Here's the part #s and prices I paid last year, (still holding pressure and performance)
Fuel Pump ADO-EP381 AC Delco 155lph (for Vortec TBI) Summit Racing $69.99
Fuel Filter KNN-PF_1000 K&N Summit Racing $11.99
Suction strainer ADO-TS6 AC Delco Summit Racing $8.99
