DESCRIPTION
This document will explain the removal of the fuel delivery pressure sensor and harness pigtail on the A26 engine. The early built

A26 engines had the fuel delivery pressure sensor installed in the engine mounted fuel filter housing (Figure #1) however, the

ECM never monitored the signal from it. Later the sensor was removed, the port was plugged, and the engine harness was

modified to remove the pigtail and the connector for it.
