Oh, and I forgot about the fuel pump.
Your current system has 30psi for the EFI, you need 5-9psi for the carb.
I think the '88 Rangers still have the 2 pump system, lift pump in tank and high pressure pump in the frame rail.
So you can remove the high pressure pump, need to connect the two hoses together.
Lift pump should supply enough fuel pressure.
Return fuel line won't be used.
The computer is what turns the fuel pump on and off, so with out it you will have to use another method.
Electric fuel pumps can be dangerous, if you are in an accident or roll over they can keep pumping fuel out of broken lines.
Your Ranger does have an inertia switch, which should cut power to the fuel pump in an accident or roll over, but...............it is your life.
What was done with electric fuel pumps and carbs was to use the oil pressure switch to turn on and off the Fuel pump power.
When you have oil pressure pump comes on, when no oil pressure pump goes off.
'88 with have an oil pressure switch, so it is on or off, not like a sender that shows when pressure goes up and down.
The switch is a ground for the gauge, when there is oil pressure switch closes and grounds the gauge, it's needle goes up to 1/4 or so and stays there.
The fuel pump relay powers the fuel pump, normally the computer grounds this relay when engine starts, so simple wiring to get oil pressure switch to do the same thing.
You need a diode on the new wire so the power doesn't flow back to dash board gauge.
