The Cummins 3282437 is the genuine AFC boost reference hose for 1989-1993 Dodge Ram 250 and 350 trucks with the 5.9L 12-valve Cummins. It carries intake boost pressure to the air fuel control (AFC) diaphragm on top of the Bosch VE injection pump.

The AFC uses that boost signal to add fuel as boost builds, so a cracked, brittle or leaking hose can hurt power and drivability. This OE line restores the factory signal path and is a smart replacement any time the VE pump or AFC is serviced.

• Genuine Cummins Part: OE hose built to the factory specification.
• Accurate Boost Signal: Feeds boost pressure to the AFC so fueling tracks engine load.
• Direct Fit: Routes and connects like the original line.
• Restores AFC Function: A sealed line lets the AFC add fuel correctly under boost.
• Service Ready: A good replacement during VE pump or AFC work.
