Attached screen shot is from S10 TBI.
It has the setup for the pump.
If you want to go this route, I can tell you how to setup. Seems difficult but it really isn't. Just take good measurements and some finesse for the sender unit to keep your gas gauge accurate.
If you look at line layout, supply is 3/8 and return is 1/2. If that's not the case, then supply is 5/16 and return is 3/8. I don't have one in front of me. The best scenario is supply 3/8 and return of 1/2. The TBI pump is designed to run full on. The pressure regulator on the TBI unit is 9 psi and there is no rail, it's designed to run full on during engine operation.
On the power feed for the TBI is: ECU energized about 8 seconds prior to start and then when "key on engine on", power is live to the oil pressure switch. From the oil pressure switch is the electrical feed to the Pump.
Pump operation stops when key is turned to off. So you don't have to worry about pump failure, pump is not designed to "rest". When engine is on, it is on and stays full on. It is a bypass pump system, it is designed to not shut off until key turned to "off".
