Have you seen many misreading gauges?


The last few tanks , mine is reading like I am getting 35mpg. approx 300 mi. since fill and still 3/4 full. Used to show less than 1/2 at 300 mi.

Had it to dealer last week and problem was the sending unit.


Pt # 25326856


Anyone having this sort of problem may want to have it checked before warranty runs out as the unit is quite expensive.


$387 retail


$193 GM parts direct

I had a Dodge Cummins before this, and my fuel guage never did work right from the day I owned it (bought used w/ 100,000 on it).


I never did have it fixed for the same reason. It was expensive, and I just learned to live with it.


Is this some kind of common problem with diesel fuel? Do they eat fuel sendors for some reason???
