When Do You Need a Diesel Delivery Valve Replacement?

A delivery valve controls fuel pressure at the end of the injector pump’s high-pressure stroke. Signs that a replacement is due include hard starting, loss of low-end torque, excessive smoke at idle, and unstable idle speed. 

Worn or damaged valve seats allow fuel to leak back into the pump body. Spring fatigue leads to erratic fuel delivery under load. Replacing a weak or damaged delivery valve restores fuel-rail pressure, smooth idle quality, and reliable cold starts.
