1st Gen Cummins 50hp new Bosch OEM injector for 1989-93 6BT engines (also run great on 4BT engines running a VE rotary fuel injection pump). These injectors have the perfect amount of fuel for daily driving, towing and fuel mileage, enough fuel for 50 RWHP. These injectors come with a 7mm nozzle and a 1.5mm nozzle washer (D3920174) If you have 9mm nozzles in your application you will need to order nozzle sleeve washers to fill the gap (pn#D3919358). Earlier applications had 9mm injector nozzles and therefore 9mm bores in the head. Because of the 9mm bore heads, Cummins experienced head cracking problems. All newer applications 1992+ and if the heads were serviced or replaced should have the updated 7mm injector bore heads. It's always a good idea to verify before ordering, all you have to do is measure with calipers across the nozzle tip.
