Early '92 Fuel gauge issues

[torxxx]

I've been fighting this gas gauge issue for a while now, if I keep it above a half tank the gauge works just fine. Anything below a 1/2 the gauge works when it wants to. It doesnt seem to be related to any shock to the system (hitting a pot hole for example) I tested the fuel level sender with a potentiometer and it appears to function the way the FSM says its supposed to.

I guess what my question is, was there any year specific issues/common problems that occured in the fuel system on the SVX's wth MFG date of 91-92?

I've got some long drives ahead of me this summer and having a gas gauge that works would be a nice thing considering Alaska has very few gas stations inbetween the big cities..

thanks in advance
