From 1989-1993 The injection pumps were the BOSH VE.
The Cummins B Series is a family of straight-4 and straight-6 diesel truck and industrial piston engines. The B Series is known for displacing "one liter per cylinder" because of the popular 3.9 L straight-4 and 5.9 L straight-6. A 3.3 L straight-4 is also available. The B Series is widely used in many segments, including pickup trucks (the Dodge Ram), buses, military vehicles, construction equipment, and marine. The engine was originally designed by Cummins and Case Corporation for commercial truck applications, and appeared in a light-duty truck, the Dodge Ram, in 1989. This was not the first engine to appear in Dodges as a Diesel option. Mid-70's D models offered the rare, underpowered, Mitsubishi non-turbo diesel. Every Cummins powered Dodge Pickup (since initial production in 1989) has come equipped with a turbocharger. It uses a gear-drive camshaft for extra reliability. Also specified is a deep-skirt engine block and extremely strong connecting rods. A Holset turbocharger is used. The original B Series was updated with 24 valves and an electronic engine management system to become the ISB in 1998.
The Dodge RAM Cummins 5.9L Diesel with the VE Fuel Injection system.
The 6BT 5.9 L B5.9 aka the Cummins "12-Valve" was the first member of the "B" engine family to be used in a light truck vehicle. This engine started life in 1984 as an agricultural engine, for use in Case agricultural equipment by a joint venture between Cummins Engine Corp. and Case called Consolidated Diesel Corp. Appearing in the 1989-1998.5 Dodge Ram pickup truck, it quickly became a popular alternative to the large V8 gasoline engines normally used in full-size pickup trucks, while producing nearly double the torque at low engine speeds. Another distinct advantage for the diesel is extremely efficient fuel mileage(also nearly double the gasser).
This engine is also used in the Dennis Dart midibus since 1989 as well as in light to medium sized commercial trucks and buses. It used Bosch Direct Fuel Injection. The injection pumps were VE from 1989-1993 and the famous P7100 from 1994-1998.5, before going to the Cummins Electronic VP44 ISB 5.9 in 1998. In Dodge Ram pickups, the engines produced 160 hp (119 kW) and 400 lb·ft (542 N·m) from '89-'93. They produced 160–215 horsepower (119–160 kW) and 400–440 ft·lbf (542-597 N·m) between 1994-1998.5 depending on year and transmission option.
