Need some HATZIE help! EFI Pump Power?
In the middle of converting 85 to EFI. Installed new 87 tanks, sending units, EP381 pumps, 87+ selector switch, 6 port pollack motorized valve.
How do I power the pumps? Do they need a dedicated power source and how do they switch over when the tanks are switched. I read the diagrams for the TBI trucks but that uses the OEM ECM which I don't have. Thanks in advance! @hatzie Since posting this, I found out the pumps draw 5 amp @45psi so tapping into the hot wire on the sending unit should be fine. Correct me if I'm wrong. Thanks Last edited by SunSoaked; 10-12-2021 at 04:15 PM. |
