EMPI 40mm HPMX Single Carburetor Kit — Type 1 Dual Port | VW Beetle, Super Beetle, Ghia, Bus & Thing (47-7315-0)

Weber IDF performance without the Weber price. The EMPI 40mm HPMX Single Carburetor Kit (47-7315-0) is the bolt-on induction upgrade for your Type 1 engine, built on EMPI's IDF-pattern HPMX carburetor — same 40/44mm bore, same tuning parts, direct Weber IDF interchange for jets and accelerator components. A single-carb setup for a clean, streetable power bump.

Why builders pick HPMX

• Genuine EMPI 40mm HPMX carburetor — IDF-pattern casting that accepts standard Weber IDF jets, emulsion tubes, and pump parts, so tuning is easy and cheap.
• Complete bolt-on kit — includes the carburetor, matched intake manifold, chrome air cleaners, linkage, fuel line, and hardware.
• Even fueling, crisp throttle — a dedicated venturi setup wakes up mid-range and top-end over a tired stock center-mount carb.
• Direct Weber IDF interchange — jets and tuning parts cross straight over, so you're never hunting for oddball components.

Fitment

Confirmed fit (complete bolt-on kit) for dual-port engines in:

• Beetle — 1970-1979
• Super Beetle — 1971-1980
• Karmann Ghia — 1970-1974
• Thing — 1973-1974
• Transporter (Bus/Pickup, 1.6L) — 1968-1974

Built for dual-port cylinder heads. Confirm your heads are dual-port before ordering; the HPMX re-jets easily for a hotter cam or larger displacement.
