its probility your sending unit inside the tank either sceezed, sticking, or the float has a leak.........
or a bad ground on the wiring.........gas guages run off the draw through the ground.......

My guess would be the wiring. Getting and losing connection.

Yeppers, loose wire, and I would bet on the ground wire.

It could be just nice GM feature. I have a 2001 Chevy ZR2 and my gas gauge gets funny on me too. On another site,ZR2.com (http://www.zr2.com), they have discussed the same problem. We are not alone. http://www.jesseshunting.com/forums/style_emoticons/<#EMO_DIR#>/smiley-thumbs-up-aqua.gif

I've seen that before ,check for a bad ground ,check the connection at the fire wall under the brake booster ,A dirty connector may be the problem if so clean it out and fill the plug with dielectric grease . I hope this helps GOOD LUCK

Bill M may have a point. Our company fleet has about 8 Chevy trucks and 2 have fuel gauge problems.

If it's like my 74 chevy, live with it that dang thing hasn't worked since 1975. I've tried cleaning grounds, tighntening connections & a new switch over valve & the only thing left is the gauge itself. good luck & let me know what fixes yours & I'll try it on my truck.
