Tiffin technical service bulletin SB-58 for 2018 Tiffin Bus.

Bulletin number
SB-58
Component
Fuel system, gasoline
Summary
On certain 2018 Buses, the fuel tank sending unit port was incorrectly located. This location causes the fuel gauge to read incorrectly, showing less fuel than is actually in the tank. The tank will read empty when it is still 1/4 of the way full. The repair will consist of removing the existing fuel sending unit, and installing a new sending unit properly calibrated for the port location on the tank. The repair will need to be done at a PowerGlide Service Center at no charge to customer.
