Gas gage woes

My 2000 Silverado has been doing the same thing (low fuel when full) for two years, once I use about a quarter of the tank it works fine. I've never had the check engine light come and I have close to 135K. Mine also has no power steering assist (this has only been the last seven months) when I turn the wheel left, I try to plan all my trips so I'll be making all right hand turns. A few more months driving like this and I'll be able to bench press my truck! I plan on fixing it someday when the dive season ends but my season runs from January 1st to December 31st. so it doesn't leave me much time.

My '00 Silverado did that (low fuel light/gauge after filling up) until about a month ago when I had to replace the fuel pump (and sending unit)... now it works fine. Unfortunately, my friend's Silverado had the same problem but replacing the pump/sender assembly didn't fix it... his had a problem in the gauge cluster. I think they spent $700 parts & labor on the pump assembly (so did I) and then $500(?) on the gauge cluster. I decided to just use the trip meter for two years until the pump failed... not spend $700 to fix the gas gauge and be wrong about the sender! David
