Fuel Pump

If the tank is full or half full it still does it, maybe about 2 lines then when i'm on level ground it's back to normal.

I'll bet you my 99 malibu the gage goes up when the car's pointed downhill. It's just the nature of the beast. It's hard to be precise when you're measuring the level of a liquid in a moving vehicle. The only time you really get a good reading (assuming F is full and E is in fact empty) is when you're level and your acceleration in any direction is 0.

I had a 87 camaro and the fuel gauge moved around alot while going uphills and down hills. My 98 bu does the same thing, now quite as fast but it does. My g\f's drive way is at a 15 deg incline and it shows i have atleast an 1\8 if not more less till i get on level ground. I just figure the resistance in the fuel gauge is less causing it to move around more then other cars.

O.k. nicc, speaking about speed. What can i do to add some horses to my bu without spending to much money.
