# Service bulletin SB\-58

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10133217
- Published by NHTSA: 2018\-04\-16
- Manufacturer's number: SB\-58

## NHTSA's 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.
