Ok here is my question, and I know some people have touch a little on the subject but here it is.
I have an EFI Bronco that is going to race class 3, I am putting a 33Gal ATL fuel cell in the rear and I need to replace the stock intank fuel pump. My first question about that fuel pump is it High PSI or Low PSI high volume? The Pump on the frame rail is a High PSI unit around 40PSI or at least close to that. What are you guys using to replace the intank pump when you put a fuel cell in your Ford Bronco or F150?

I have used this pump in our 7s Ranger for the past two years without a problem.
I know it's not a Bronco, but the concept is the same. Our truck has a SOHC 4.0L EFI engine.
It stated in the owner's manual the pump needs to be mounted at or below the level of the bottom of the fuel cell. It's mounted on the frame rail about 1/3 the way up from the bottom of the cell. When I talked to Aeromotive about the pump location, they suggested running an oversized feed line (-10) to the pump to reduce fuel starvation to the pump. So far no problems, it will push out a constant 45 psi to the stock regulator day in and day out.
Granted this pump is a bit pricey ($300.00) but so far it has proven itself to me to be reliable. I was using the stock Ranger inline pumps and gave up on them after replacing the fourth one. The only thing I did was add a one way check valve on the outlet side of the pump to prevent fuel from siphoning back into the cell when the truck sits for an extended period of time. I bought the pump from Summit's website.

I have seen that pump but it seems to be for a single pump system not a two pump system. I just need to replace the intank pump. Also in my application it would be very hard to place the pump below the fuel cell pickup. The fuel cell is in the stock tank location to keep the weight closer to the ground.

Ford did a two pump system in the EFI OJB'S?
If they did, the in-tank pump should be a low pressure unit.
Really hard to beat OE for MTBF. Why not adapt the stock in-tank pump to the fuel cell?
