Thanks to all who provided suggestions.


your experience is typical with replacement aftermarket fuel sending units across the board. Spectre started out trying to correct the issue but has failed. Trust mo on this as we have spent HOURS trying to make them read correctly on numerous vehicles.
IMO you have two choices.
1. live with it knowing that 7/8 is full and hoping that E leaves a couples of gallons of reserve
or
2. Buy a device from tanks that allows you to compensate for the S/units discrepancies. Not too bad to install and fixes the issue. certainly less time consuming than trying to make the units read correctly.
