Gas gauge doesn't move!

[Crown1]

Hello to All My 1999 Suburban 1500 gas gauge doesn't move from full after driving over 100 miles. Can someone tell me what the problem maybe it just started on 3/21/05.

Search this forum with the words 'gas guage'. You'll find several threads on this subject. I had the same problem on my 1999 Suburban K1500. From what I've read, a clogged fuel filter will cause the fuel pump to work extra hard, and get hot. This heat can wreak havoc on the sending unit and basically ruins it. I had a local shop drop my tank and replace just the fuel guage sending unit. The unit cost $147.00. Total repair cost me just under $300.00. The key is to replace your fuel filter every 30,000 miles or sooner. The clogged fuel filter, if ignored can also cause your fuel pump to fail. Then you're talking $300.00 in parts alone. Good luck.
