Fuel Gauge Characteristics
My question is based on this TSB. I believe that my '01 XLT Off-Road is affected by this. After I fill up, my gauge is down to 3/4's after 28-30 miles. It continues to drop rather quickly to 1/4 tank, after only 125-150 miles. It then will sit on 1/4 tank forever. Even in the E-red zone, I still have anywhere between 7-11 gallons left in the tank.
Has anyone had work done based on this TSB? Did it really help the condition?
Fuel Pump/Sender - Erratic Gauge Operation
ELECTRICAL - FUEL GAUGE - FUEL GAUGE DROPS
FROM "FULL" TOO FAST - FUEL GAUGE INDICATES
LESS THAN THE ACTUAL FUEL LEFT IN THE
TANK - VEHICLES EQUIPPED WITH 2.3L, 3.0L GAS
OR 4.0L SOHC ENGINE - VEHICLES PRODUCED
BEFORE 3/26/2001 ONLY
This article is being republished in its entirety to update the engine applications.
Some vehicles equipped with a 2.3L, 3.0L gas, or 4.0L SOHC engine built before 3/26/2001 may exhibit a fuel gauge that drops from "FULL" too fast or indicates less than the actual fuel left in the tank (excessive tank reserve). This may be reported by the customer as perceived poor fuel economy or that the fuel tank will not hold the advertised capacity. This may be caused by the accuracy of the sending unit on the fuel pump assembly.
Verify condition. Be advised, the fuel tank WILL hold the advertised capacity. If normal diagnostics cannot pinpoint condition, remove the existing fuel pump assembly and replace it with a more accurate fuel pump assembly. Refer to the following Service Procedure for details.
Verify vehicle exhibits either fuel gauge dropping off from "FULL" quickly, fuel gauge reading inaccurate, excessive fuel consumption, customer assuming fuel tank is wrong size, and/or at "EMPTY" there is excessive amount of fuel within reserve.
If any or all conditions are present and normal diagnostics cannot pinpoint condition, remove existing fuel pump assembly and replace with revised fuel pump assembly. Refer to the parts table in this article for correct listing.
