The Cummins Fuel Supply Hose is the hose to check when a Cummins engine loses prime or cranks long after sitting. Cracks in a supply hose often pull air in long before they leak fuel out. Over time heat and age harden the hose, opening the door to air leaks that cause hard starts, rough running, and loss of prime after the truck sits. Routing the Cummins 4009781 in place of a hardened hose restores a sealed, flexible supply to the pump.
