Bad Carter P74029 Fuel Pump from RockAuto

You want to gravity feed the pump, so the lower the better. Also normally the filter is only installed after the pump, not before, as it can cause a restriction. If you dont have a sock filter at the tank feed you can run a filter before the pump, but it should not be for very fine particles, just a trash filter. Myself I would lose it as long as your tank and lines are in good condition. Check with the pump MFG and see what they recommend.

I was advised to install a filter between the pump and tank to protect the pump.
This filter Crown Automotive - Fuel Filter Kit - Fits 1980 to 1986 CJ:With 2.5L engine - 4WheelParts.com is to be installed between the pump and regulator. Can it be installed right next to the pump? If it can I can just plumb it back to the tank without having the run another line back up to the engine bay where the regulator is.

I am planning to move the pump from the frame rail to right behind the tank where the outlet is.
I was thinking of using the Airtex E8090 but I talked to Airtex and they said the E8090 is not big enough and recommend the E84070N for my application. The only problem is that it will hang down below the tank since the connections are above the pump.
The Holley 12-801-1 has similar flow and pressure specs and has the connections at the bottom. Are there any other pumps with the connections at the bottom?
Droptop70ss - What OEM pump is that? Do you know a part number?

The pump that failed looked like this:
Attachment 124535
The connections are low on it and I could mount it near the tank.

The Holley pumps are actual gear pumps, much like a GM oil pump, and what is used on high pressure EFI systems. Much higher flow and a constant, smooth flow of gas, and they have a built-in recirculation valve to prevent really high pressures at idle. But a recirculation path from up near the carb back to the tank may prevent vapor lock-type problems.
