PS22 (FOTZ-9A299-DB) Fuel Level Sender

Apparently, this fits all '90-96 Broncos. '90-97 F-series use PS19 in the front tank & PS23 in the rear. List is ~$80 tax from Ford; I paid ~$55 total from Parts Plus. It should read ~160 Ohms Full (Up), ~16 Ohms Empty (Down, as shown).

Before buying a new one, try disassembling the plastic cover from the metal plate & polishing all the contact surfaces with super-fine steel wool to remove the fuel deposits that can interfere with the electrical flow.

Before buying craptasmic cheapo aftermarket parts, check for coupons & service offers from Ford.

TSB 88-18-03 Fuel Gauge Erratic

Publication Date: AUGUST 31, 1988

FORD: 1987-88 MUSTANG, TAURUS
LINCOLN-MERCURY: 1987-88 SABLE
1988 LINCOLN TOWN CAR
LIGHT TRUCK: 1987-88 BRONCO, F-SERIES

ISSUE: An erratic fuel gauge needle when the fuel tank is 1/2 to 1/4 full may be caused by excessive wear of the resistive film on the fuel pump sender assembly. The wear occurs during transporting of the vehicles via rail or truck over long distances. The fuel gauge will indicate correctly from a full tank to about 1/2 or 1/4 tank of fuel. When the fuel gauge needle is below the 1/2 to 1/4 tank range the needle will swing all the way above the full mark on the fuel gauge.

ACTION: To correct this, install a new fuel pump sender assembly. Refer to the appropriate 1988 Car/Light Truck Shop Manual, Section 24 for detailed service information. Refer to the following fuel pump sender application chart for the correct service part number.
