1988 Ford Ranger - New to me, What is this?

The pump doesn't need to cycle as long as the pump cannot over come the float valve. If the pump pressure is too high then a pressure regulator might be needed. A return line system is always better but should not be required.

That truck was supposed to have a mechanical pump, so it wouldn't have had a relay. That's probably why it is wired stupid.

Yep makes sense.... I appreciate your time and replies, the both of you.

If you guys were around here.. on me.

Good luck with it - might run pretty nice with that header!

I've run many low pressure electric fuel pumps over the years and don't believe I ever used a relay. Just key on power. They will run any time the key is on... no cycling on and off. If it would make you feel better... throw a pressure gauge on the fuel line... 6-8 psi is probably all you need. Higher then that you might want to add a pressure regulator. If you had to much pressure currently you would know it... it would run pig rich and probably dripping fuel everywhere.

judging by the block casting... I would say that the block was meant to be efi... and someone put a carb on in it's place.

as far as the vacuum lines... I'm guessing most systems that require vacuum are long gone already. I would buy a handful of vacuum caps and just cap what you don't need and call it a day.

I have no direct experience with this, but I have read somewhere that one of the lower intakes used on the EFI 2.3L was the same as the carb lower intake, and the full extent of the physical modifications to the engine needed to convert from EFI to carb is to remove the upper intake and bolt a carb down in its place.

Sure looks like an efi valve cover to me-

Yep, some body cobbled that fuel system together, as that looks like an efi- valve cover, block, wide open unused space...

Definitely a late efi block, maybe even an early 8-plug 2.3. I think they still had a hole for the distributor. Probably blew up the 2.0, threw in a 2.3 block and used the 2.0 head, intake and distributor. Probably had to use the 2.0 auxiliary shaft and maybe its oil pump setup. No fuel pump location so they used a cheap in line electric pump only rated for carbs so no regulator or return lines. I can't see it but a give away for me on an 8-plug block is in the alternator adjusting bracket where it bolts to the block. 4-plug motors have 3 bolts and 8-plug motors have 4 bolts. Maybe if it's an 8-plug block they used the roller camshaft out of it.
