Since I have decided to go with a carb instead of a TBI FI - the horror stories on both the Holley and FiTechI FB groups outweighed the success stories. I pulled the Holley FI pump/sending unit assembly from my tank yesterday. This unit is a direct drop-in for 63-76 A Bodies. By the numbers on the pump it was a 58PSI Walbro pump. Walbro does have a low pressure (12 PSI) in tank pump. So doing more research through Summit i found a 6PSI in tank pump from Agility Auto Parts that likely would be just what the Edlebrock could use. Doing some more research I found this pump is designed for some Ford applications. They (Agility) has a bunch of cross references for different pumps - for example, the Carter in tank P60293 and P74067, both of which Summit sells. These cross reference to being used by Ford/GM vehicles. However, Summit doesn’t list the PSI numbers for either pump. Carter does show each has a minimum pressure of 3PSI but not maximum. Guess I’ll be on the phone Monday for more info.
