Fuel tank/pump issue?

[JAY]

During hard accelleration has your sy or ty ever cutout when fuel level is around 1/4 of a tank? It acts like it is sloshing away and it will basically fall on it face and then regain once the fuel sloshes back. I changed the fuel filter. I still have the stock tank and fuel pump.

Yep,

Normal. Worse on Sy's, not so much on Ty's.

That's why I went to a sump and an external pump.

Really bad on the SoGT's as well.
When I first got my GT new in '92 I was still fairly young and ran it low on gas all the time. When I turned a left corner or accellerated hard it wold cut out just as you explained. The lower the fuel got, the easier it would happen. For me it was sort of an IDIOT light telling me to get gas before you are stranded.

Maybe it was some sort of early GM warning system in the testing stages....LOL
It sure worked on me. I am rarely below a half tank anymore.

I am rarely below a half tank anymore.

Same here, I used to be able to drive with as little as a quarter of a tank with no problems until I lowered my truck and lost the 3/4 ton pickup look. I have read that GM jacked the rear of the truck as high as they did to help minimumize the "fuel slosh" under hard acceleration. Everyone knows that it wasn't for increased cargo capacity... I start looking for a gas station as soon as I get down to half a tank.
