Description

CUMMINS INDUSTRIAL:
• Cummins 4B/4BT/4BTA/6B B Series Diesel — 4BT3.9 or 6BT5.9 (1984-2005)
• Cummins 6BT/6BTA B Series Diesel — 4BT3.9 or 6BT5.9 (1984-2005)

INDUSTRIAL EQUIPMENT:

IMPORTANT:
ROTARY PUMP (Bosch VE) variant mechanical lift pump for Cummins B-Series engines. Diaphragm-style design with 12mm inlet and 14mm outlet fittings. CRITICAL: Do NOT use for inline pump (Bosch P) systems — use C3918000 instead. Cross-references 3928143 and 3970880.
For 1989-1993 Dodge Ram Cummins 12V trucks with VE injection pump, and Cummins 4BT/6BT industrial applications with VE pump. The VE vs P-pump distinction is the #1 ordering mistake. VE pumps are identified by their single cylindrical body; P-pumps have multiple individual plungers. Failure symptoms: hard starting, fuel starvation, power loss, stalling.
⚠️ For VE (rotary) pump ONLY. NOT for P-pump (P7100) — use C4988747 or C3918000.
