# Service bulletin TSB140019

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.

## NHTSA's summary

This document, in conjunction with the information provided within the manuals listed in Table 1 provides inspection and repair guidelines following the malfunction of an XPI fuel pump pumping plunger and/or roller tappet assembly. The level of progressive damage to the fuel pump and other engine components will vary with every incident; however, the repair direction will depend on only a few key criteria. Previous versions of this document provided specific repair directions according to the vintage of the fuel pump and type of pumping plungers. Repair directions have now been made common and apply to all fuel pumps regardless of vintage, pumping plunger type, or tappet roller assembly type. This is a revision to a previously submitted communication.
