Probably the sending unit.
how do i go about fixing my fuel gauge in my 1986 ford f150
If it takes 30.00 to top off the gas tank, but the gas gauge shows full on an 85 F150 4.9 Straight 6, it is likely that the gauge is not reading correctly. Replacing the gauge cable can remedy this.
The headlights in the Ford F150 may have stopped working due to a bad fuse or bulb. Check these and if it doesn't fix the problem visit a mechanic.
most likely would be a bad turn signal flasher
The temperature gauge sensor on the 2002 F150 is located on the driver's side of the vehicle and under the intake. This is almost impossible to remove without removing the intake itself.
I believe it is 19 gallons ( U.S. ) front tank on your 1987 F150 long bed
THERE IS NO GAUGE CHECK IT WHEN ITS COOL TAKE THE CAP OFF AND LOOK IN DO NOT DO THIS IF THE ENGINE IS WARM IT WILL SCALD YOU
The oil pressure sensor for a 1987 F150 could be bad. If the sensor is good and the pressure has actually dropped then the oil pump may be bad again.
