The pumps I referenced need filters in front of them and the filters ship with the pumps. Any vane pump should have a filter in front of it. The pumps listed will deadhead without problems, there's no need for a return line. It doesn't show, but I capped the selector vale openings with push - on caps. The pumps are fed by the original lines to the selector, and the same switch picks up the relay for AUX. In this way you can revert to OEM for bolting a mechanical pump on and replacing the three hoses... no cutting necessary. Cured vapor lock in Georgia in July - August. Also, if you turn the ignition on for ten or fifteen seconds before cranking, it primes the carb for a quick start.
Go down to the Men's Mall and find an '05 or so Ranger pickup with a 3 liter Vulcan motor. Look on the firewall in the cab just above the passenger toeboard under the carpet. Under a guard bolted to the firewall is the turnover switch. The Ford one also shuts down on a certain G-force so if you hit something but the wreck stays upright and running it'll still kill the pumps. Use it in lieu of an oil pressure switch. I say Vulcan motor because mine had one, but i suspect the four cylinder and four liter ones use the same setup.
