View Full Version : Fuel Pump Issue
12-31-2007, 12:48 AM
I just bought a Bronco2 thats been converted to a 4 liter but its not getting enough fuel pressure. it still has the frame rail pump, should i just put a 4 liter pump in the tank and will it run off of the power that all ready runs to the tank? I read some where to leave the frame rail pump in and have a 4 liter pump in the tank. Just looking for some advice thanks[cheers]

When fords have a fram rail pump, they also have a in tank pump. The tank pump is for volume and the rail pump is for preasure. It sounds like one of the pumps isn't working. Most likely the tank pump.

personally i would go with the explorer fuel system , but yer existing fuel pump should work , do u have a fuel press. guage to hook up to the rail , note the fuel pressure regulator at the end of the rail is also known to fail frequently , try un-hooking the Vac line or test key on engine off fuel pressure
