Question about 1987 Ford F 150

1987 ford 150 rear fuel tank not working

Hello, When I switch to the rear tank the gauge goes to past full, then drops to E. Even though I have it on the rear tank it keep drawing fuel from the front. I have switched the switch back and forth many times like suggested and it still does the same. Maybe once in awhile it will stay at 1/2 tank "guage" but continues to draw from the front. I have also banged on the fuel tank etc like suggested. The truck only has 64k miles on it. Any help would be great.. Thank you very much.

Remove the fuel selector switch from the dash, you can test it with a simple $8.00 swing volt/ohm meter. Its probably bad. Note there is a valve switch under the drivers door jam that selects witch fuel line to use, that is the second place to look. Hope it works..

The gas gauge for the front tank on my 1992 F150 is stuck past full


You probably have a ground wire not making contact to ground on the front tank sending unit. OR the sending unit itself inside the tank is faulty. Either way, when a gas guage goes to full all the time (empty or full), this indicates that NO ground is available for the sending unit.

The gas gauge for the front tank on my 1992 F150 is stuck past full


replace front fuel pump because gauge is made into fuel pump and not serviceable. Or poor boy way of getting by would be fill front tank with gas reset mileage drive normal for a day. refill again with gas note gallons used and mileage driven for average miles per gallon. front tank should be around 17 gallons multiply by mile per gallon you figured

Fuel Gauge wont move past 3/4 tank even with full tank


There is no easy fix.
Either the gauge on the dash is faulty, or the sending unit in the tank.
The sending unit uses a float which may be getting stuck at the 3/4 mark.

Dual tank pickup. Fuel gauge doesn't work on either tank?


You just have a ground problem between the frame and tank ground. It has to be connected to a clean tab on the tank at the fuel sending unit. Check and clean them, both tanks. It gets confused and don't know what to do without a complete circuit.

My f350 1997 will not run on the rear tank . how do i go about finding what the problem is?


well, first, to find out if its the in tank fuel pump or the tank selector valve, the cheapest and probable easiest thing to do is find the selector valve under the truck and switch the incoming fuel lines. front tank to rear tank inlet, and vice versa. If the truck still doesnt run, you either have an electrical delivery problem to the in tank fuel pump or a bad fuel pump. If after switching the lines, it does run, then you need a new selector valve

Fuel Tanks reversed , Gauge not reading?


The Ford trucks were recalled for the tank switch replacement. Somehow the switches would pump fuel from one tank to the other. This would cause the one tank to overflow and or result in a fire from hot exhaust temps coming into contact with the fuel. Check the dash tank switch. It is probably bad.

Fuel Gauge Issue


I know you don't want to drop the tank and I could lie to you, but the truth is that you have to drop the tank to check and fix this problem. It really is not as hard as you may think. Even easier if you are low on gas. Putting a full tank back up is a real challenge!
So, after you pull the tank down and remove the sending unit/fuel pump, get a ohm meter and set it to Ohms. Insert the leads one into each opening on the connector on the sending unit plug. Slowly raise and lower the arm with the fuel float on it and see if your ohms fluctuate. Also notice if there is any resistance on the arm as you move it up and down. This is how you check your problem. I have seen it many times before. A new sending unit will fix this problem, though if your ohms are fluctuating and your float arm is stiff, you can temporarliy fix it with a few squirts of WD40. It will start to hang up again after a while though.
Please remember to rate this fix.
