DASPARTS Mechanical Fuel Pump 113127025D for Generator VW Beetle, Ghia & Bus — Direct-fit OEM-style

DASPARTS 113127025D is a replacement mechanical fuel pump designed to restore reliable fuel delivery on classic air-cooled Volkswagen engines used in Beetle, Ghia and early Bus models.

This direct-fit mechanical fuel pump is built to match the factory specifications for many classic VW models, offering a straightforward swap when the original unit shows wear, leaks, or diminished flow. It fits a broad range of air-cooled engines and is sized for generator-equipped vehicles; the part helps maintain steady fuel pressure for carbureted systems and makes vintage VW upkeep simpler for restorers and daily drivers alike.

Which VW models and years does this pump fit?

The DASPARTS 113127025D is compatible with numerous classic Volkswagen cars and vans equipped with generator setups. It covers Beetle, Super Beetle, Karmann Ghia, Type 3, and early Type II (Bus) applications across various engine displacements listed by factory codes.

• Beetle (standard, ragtop, sunroof, convertible): 1954–1977 depending on body type
• Super Beetle Sedan: 1971–1975
• Karmann Ghia (coupe and convertible): 1956–1974
• Type 3 Fastback and Squareback: 1962–1973
• Type II (Bus): 1955–1979; specific fitment up to 1971 for generator models
• Engine-specific coverage includes models like KAEFER 1200, 1300, 1302, 1303 with applicable years

How does this replacement pump compare to the original VW part?

This pump is manufactured as a like-for-like replacement dimensionally and functionally, matching key mounting points and inlet/outlet positions used on generator-equipped engines. It aims to deliver the same flow and diaphragm action as the OEM piece so installation is typically bolt-in with stock linkages and gaskets.

• Factory-style mounting and port locations for straightforward installation
• Mechanical diaphragm design intended for carbureted fuel systems
• Compatible with stock fuel lines and fittings used on the covered model years
• Meets performance expectations for restoration and routine maintenance

What should I check before installing this fuel pump?

Prior to installation, inspect the pump’s mating surfaces, gaskets, and fuel line condition to ensure a proper seal and safe operation. Confirm engine type (generator vs. alternator) and the pump’s orientation so you select the correct side and fitment for your VW.

• Verify your vehicle’s engine and year against the compatibility list
• Replace the pump gasket and use proper torque on the mounting bolts
• Inspect fuel lines, clamps, and filter for wear; replace if needed
• Prime and test for leaks before starting the engine

Will this pump support performance upgrades or modified engines?

For mildly tuned engines that retain a stock carburetor setup, this pump typically supplies adequate flow and pressure. However, high-performance applications with larger carburetors, dual carbs, or significant cam/boost changes may require a higher-capacity pump or additional fuel system modifications.

• Suits stock and lightly modified carbureted engines
• Not recommended as-is for heavily upgraded fuel demands
• Consider aftermarket high-flow options for dual-carb setups or performance cams
• Consult tuner specifications when building a high-power engine

Who is this for: The DASPARTS 113127025D is aimed at classic VW owners, restorers, and mechanics maintaining Beetle, Karmann Ghia, Type 3, and early Bus models that use generator-equipped engines. It’s a practical replacement for those restoring originality or solving fuel delivery issues in carbureted vintage VWs where a direct-fit mechanical pump is required.
