Description of Change: The new fuel injector groups have lower plunger and barrel contact loads due to a material and porting change to the plunger. This results in an injector that is more resistant to plunger and barrel seizures. The new barrel design also reduces the plunger/barrel fuel leakage which will result in less fuel dilution of the engine oil.
Adaptable To: The new 4P9075 Fuel Injector Group is a direct replacement for the former 7E3381 Fuel Injector Group. The former group is canceled. Chart A identifies the effectivity of the new 4P9075 Fuel Injector Group.
