i dont think there were any in my 93 ,not that i remember anyway,only time my gauge moves around much is when its around 1/4 tank or so

 

Thank you, mjd.

 

Bump - anyone seen the tray and can tell me if it would fit through?

I can't imagine the locating studs being there without a reason. GM might have saved a few pennies, so why even install them?

 

I think your gauge bouncing is more of a electrical problem than mechanical. The fuel gauge in my 95 2500ld bounces wildly some times but not others. I have gremlins in my electrical system that I haven't found yet. The ground on the tank is suspect because of the lack of corrosion resistant material. The groun to frame is another place.

 

I've searched and read the posts on the sender electrical problems. There appeared to be nothing wrong with the sender electrically or mechanically and I was not able to find any reference to tank grounding that I remember.

Unless yo are refering to the anti-static fill throat grounding, but that is isolated from the tank by the rubber filler hose. In any case, I believe that the circuit utilizing the two lead sender rheostat connection is grounded elsewhere.

If I missed something, kindly correct my ignorance. Thanks!!!

I am still curious about the anti-slosh tray and its size.

 

Mine does the samething when I come to a stop. It also reads more than full and when its empty it still has about 6gallons left.
