, 5.7L V8, Salt Lake City, UT, December 01, 2010, 19:14

is there an easy fix to the gauge reading 1/2 tank and just below that it's really empty, we found this out traveling from wisconsin back to utah.... not fun... how is this fixed ? or do i have to replace the fuel pump assembly as i was told the sensor is in the tank ? being disabled and not alot of $$$$ , i was wondering if this is an easy fix or ? thanks for all the help, used to be a mechanic,, but after having back surgery twice, no longer can crawl under it ...

    unfortuneately, the tank has to come down and the sender is part of the entire module.
    part is about 289
    labor is 2.2 hours

    You have likley one of two problems, one is a possible gauge in the instrument cluster and the second is a fuel level sending unit and both are common.The fuel sending unit is availible seperate from the the fuel pump and many GM instrument clusters are available aftermarket. A tech II scan tool would be the way to test, but in many cases the gauge will be erratic and the sender will be inaccurate.
