Wrong selection will cause unstable engine speed, insufficient fuel supply, black smoke and power loss.

When to replace
PT fuel pump assembly suffers internal component wear, pressure drift and control failure after long running hours and contaminated fuel.

Replace the matched PT pump assembly when abnormal performance appears, and inspect fuel filter and fuel lines at the same time.
