Fuel cell help needed!!!!

[PA_Bowhunter]

Just installed this bottom sump fuel cell on an 89 BII. I need to know where to locate the high pressure fuel pump. I was told that all I needed was a low pressure pump just to send the fuel to the high pressure pump,but it won"t run now. It fires but shuts down right away.Please help!

do you have the fuel return and vent ported yet?

my fuel pump just went out, and I only have one and it's in the tank, my BII is also a 89.

my 88 rangerr has two pumps.

I would think that if the fuel comes out of the bottom of the fuel cell, you would only need the high pressure pump, just try and get it close and low to the tank, or at least that is what the guys on "the power block" say, dang it miss watching those shows.


you also might want to check your relays.

I don't see the point of running a high pressure pump and a low pressure pump because the low pump only pulls a certain amount of fuel to maintain pressure and where the high pressure pump needs alot of fuel to maintain pressure.. So to me the high pressure pump would over load or pull to much fuel in each set up and the low pressure pump can't keep up to the demands of the high pressure pump.. I would think one high pressure pump would be good unless it is running a great distance...
I could be wrong ,i am not sure

in my 88 ranger it has two, one in the tank that is a low pressure, and then a high pressure one on the frame under the seat, the low pressure one is for bringing the fuel up to the high then the high sends it to the rail, I'm not sure but I think they both push the same amount, but the high pressure can't pull fuel just push it.

There are a lot of setups that run dual pumps. The gen 1 FI setups, most diesels. I'd try to get a ex pump and use that, it runs everything fine and it's just one less thing that can break.

The explorer pump will mount to a stock 1st gen in-tank sender. If you are set on the dual-pump setup, put the HP unit in the stock location. It would have sit just about under the driver's seat.

Okay thanks for info!!!

You were misled, a 1986-88 Bronc2 only needs a low pressure pump tosend fuel to the HP pump on the frame.

The problem you are having is that an '89-90 Bronco2 doesn't have a high pressure pump on the frame, the HIGH PRESSURE pump in the tank was all the had...

You need a high pressure pump to replace that low pressure one inside the fuel cell.

Sorry, I didn't mean to mislead him.
