THE HOLLEY BLACK PUMP PUSHES OUT ABOUT 14 PSI, PROBLY NOT GOING TO WORK DEPENDING ON EFI SETUP, MY 57 IS LS1 FUEL INJECTED AND CALLS FOR AROUND 60 PSI, I WENT WITH A EXTERNAL WALBRO FUEL PUMP, WITH PUSH LOK HOSE HIGH PRESSURE HOSE. YOU CAN GET THE WALBRO PUMPS FOR AROUND 100.00 NEW

Nope will not work, even a throttle body injection requires 15/16lbs of pressures to work properly, EFI's require 40 plus lbs of push and return lines. EFI nozzles are usually 32 to 40 lb nozzles, that why most people put in the tank fuel pumps on conversions. I have one for my 1979 El Camino but haven't installed it yet, it requires a tank made for a in the tank pump, a 1992 yellow plug computer, and a closed loop painless wiring harness, that's one of the reasdons i haven't installed it yet. it's definately not a couple hrs installation.
