# Service bulletin TSB\-90\-08\-25

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.

- [01146920366681](/bulletins/10228399.md), 2023-01-03, Service bulletin: FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. When diagnosing the condition listed above on a common rail diesel vehicle, if no root cause is found after all GFF diagnostic procedures have been performed, it may be necessary to check for metallic particles in the high pressure fuel pump using the procedure in the Service section of this bulletin.
- [01146220361693](/bulletins/10228392.md), 2023-01-03, Service bulletin: FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F \(\-7° C\), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation. This may clog the fuel filter or in\-tank filter, preventing the engine from operating properly. No. 2 Diesel is blended by refineries to various levels of winterization \(minimum useable temperature\) based on month, geographical location, and the 10th percentile minimum ambient air temperature for the given region. Although rare, during sudden periods of extreme low temperatures \(record lows\), fuel stations may not be adequately prepared with No. 2 Diesel fuel with sufficient winterization to resist wax formation or ?gelling?.

Contaminated or incorrect fuel can cause performance, drivability, and/or fuel delivery problems. Additional component replacement may be necessary to ensure that no contamination or debris remains after repair. Reasons for fuel contamination can include: water ingress in the fuel station?s holding tanks, errors made in fuel transport, or incorrect fuel has been dispensed into the vehicle.
