Not another fuel guage thread!
I just want to know why mine only acts up after a 45 minute or longer drive. Never does it on in-town trips.
Yes Ive tried techron and use good gas.

From the service manual:
Note: The 1997 through 2002 and early built 2003 Corvettes (Starting on November 25, 2002 with vehicle identification number 35111542, all Corvettes and all 2004 XLR use the FFS fuel system) without the FFS system did not have a secondary regulator which prevents the siphoning of fuel (LH to RH) after the vehicle is turned off. The siphoning could balance the fuel such that, at start-up, the sender voltages could be similar. That is why there is a 40 minute timer on the P1431 DTC on these vehicles to allow the fuel to transfer to the LH tank after start-up.

Damn usually after I turn the car off and back on the gauge is working. It hasnt started working again this time. Ive used techron several times in the past. I filled up yesterday and the pump keep shutting off on me.
