★ Replica of the original AC fuel pump as originally fitted to Willys MB, Ford GPW and early CJ models. The glass bowl is an inverted sediment bowl that allows visual inspection of fuel flow.

Application

Fits Willys MB (1941-1945), Ford GPW (1941-1945), Willys CJ-2A (1946-1949), CJ-3A (1949-1953) with L-head 134 ci engine. Also suitable for CJ-3B (1953-1964), M38, M38A1, CJ-5 (1955-1971) and CJ-6 with F-head 134 ci engine where no vacuum connection for windscreen wipers is required. For vehicles with vacuum windscreen wipers, a dual-action pump with vacuum port is necessary.

Installation notes

Pay attention to correct mounting distance from pump arm to mounting face (1-1/4" to centre). For certain applications (CJ-3A, CJV-35/U, M38), a spacer between pump and engine block is required — absence of this spacer can cause excessive fuel pressure. Apply a thin layer of sealant to the block side of the gasket. Ensure cam lobe is under pump arm during installation. Hand primer lever is useful after prolonged standing to fill carburettor without loading starter motor.

Compatibility

This is a single-action pump WITHOUT vacuum port. Not suitable for vehicles with vacuum-operated windscreen wipers (various M38, M38A1, CJ-3B with vacuum wipers). For those applications, a dual-action pump (AC 9353, AC 4032, AC 4080) is required. Fits both L-head (flathead) and F-head (overhead valve) 134 ci engines. The glass bowl is characteristic of early specifications — later AC pumps (1960s-70s) used metal bowls.

Historical context

AC fuel pumps with glass bowl were standard on the Willys MB and Ford GPW until 1945, and on early CJ-2A and CJ-3A models. The glass bowl — actually an inverted sediment bowl — allowed visual inspection of fuel supply and sediment, a practical feature in times of variable fuel quality during and shortly after WWII.
