I own a 4x4 1987 ford bronco ii. i have no fuel flow in the vehicle, i know i need to replace the tank, but i want to replace the sending unit aswell. i discovered the fuel pump is not on that particular sending unit. So my question is: what kind of fuel pump do i have? i would like a part number. and also, i have a fuel pump resevoir assembly that is broken on my vehicle (the casing is busted) but mine has a 2.9l v6 and i didn't think this year had a fuel resevoir on the chassis like that, can you answer that question aswell?

When Ford Went to fuel injection on the 2.9 L V-6 they manufactured them with two fuel pumps.Pump number one is located in the fuel tank on a hanger complete with fuel gauge sending unit.This pump is used for volume.Fuel pump two is located on the drivers side almost directly under the drivers floor pan area nestled inside the frame.This pump is used for high pressure that is required for fuel injection.Your problem may lie in the pressure pump.Also the 2.9 L has a vacuum controlled pressure regulator that is located on the right hanf topside of the engine towards the backof the intake plenum on the fuel rail.It has two screws mounting it and is round with one single preformed vaccum line going to it.These have a filter screen that can become cloggedand be pushed into the regulator restricting fuel flow or the diaphragm just wears out.Check these three things out and ill bet you be running in no time.The bronco II`s also have two fuel filters one mounted on the drivers side mid vehicle nestle within the frame check it also.Well I hope this helps.

Good Luck...........

2 reason
1. your fuel tank is rusty it deliever rusty fuel to your tank
2. your pump motor get jamed or need to replaced thats why it blowing your pump commanding relays..

probably in the fuel tank,

try replacing the fuel filters and cleaning the carb/injectors

need to remove tank and clean rust and junk out of it its sucking up on the sock in the tank and blocking fuel flow

This problem in a Ford is caused by a defective fuel gauge sending unit inside the fuel tank, the tank must be removed to replace the sending unit.

Either the gauge is bad, or the fuel tank sending unit is bad. Also check the wiring to the sending unit.

Fuse panel is located inside vehicle under dashboard on driver side. Fussible relays and links are located under the hood on the front of vehicle on drivers side.

The problem is most likly the sending unit in the fuel tank but check the float. drain tank, there are two bolt in the straps on the fuel tank lossen enuf to lower tank to get to top to unplug wires and fuel lines once tank is on the ground thee is a ring on the top of tank holding the pump and sending unit in tap ring around with a screw driver to lossen once you have that off just pull unit out of tank and follow directions that come with sending unit. reverse removal procedure. good luck.

I need to know if the other gauges are accurate. There is a voltage regulator mounted on the back side of the dash that can go bad and often does, that will make the other gauges inaccurate also.
