DASPARTS Mechanical Fuel Pump for VW Beetle Ghia Bus — 113127025D Generator-Era Direct Fit, Low-Pressure Diaphragm

DASPARTS 113127025D is a mechanical fuel pump engineered as a direct-fit replacement for classic VW air-cooled engines used with a generator, covering Beetle, Ghia and Bus models through the early 1970s.

This replacement fuel pump is made to restore reliable fuel delivery on vintage Volkswagen engines that used generator-style electrical systems. It matches the original mounting and port locations for straightforward swap-in installation, and the part number 113127025D corresponds to a wide range of VW Kaefer, Type 1, Type 2 and Type 3 vehicles produced from the 1950s through the mid-1970s. The item is offered by DASPARTS and is suitable for owners restoring classic VWs or maintaining a daily driver with period-correct parts.

Will this fuel pump fit my VW Beetle, Ghia, or Bus?

Yes — the 113127025D is specified for many air-cooled VW models that originally used a generator configuration. Confirm fit by checking your engine’s model year and the original part number if possible. If your vehicle is listed among the supported model ranges, this unit will align with the factory mounting pattern and fuel ports.

• Fits VW Beetle Sedan, Ragtop, Sunroof and Convertible across listed years
• Compatible with Super Beetle sedan and multiple Karmann Ghia years
• Also fits Type II (Bus) and Type 3 Fastback/Squareback models within the stated ranges
• Matches original 113127025D part number used on generator-era engines

How does the pump perform and what materials are used?

The pump delivers the low-pressure fuel flow typical of original mechanical pumps for carbureted VW engines. It uses durable housing materials and internal diaphragms designed for long service under normal operating conditions. While not a high-pressure modern fuel injection pump, it restores factory-spec fuel delivery for carburetor systems.

• Mechanical diaphragm design for consistent low-pressure output
• Metal housing matched to OEM mounting and bracket interfaces
• Seals and diaphragms made to withstand standard gasoline and engine heat

What should I know about installation and maintenance?

Installation is straightforward for anyone familiar with older VW engines; the pump mounts to the engine case where the original unit sat and connects to the carburetor and fuel tank lines. Basic tools and a torque specification for the mounting bolts are typically all that's required. Routine checks of mounting bolts, fuel line clamps and diaphragm condition will prolong service life.

• Direct-fit bolt pattern for OEM-style replacement — no modifications expected
• Attach inlet and outlet fuel lines with proper clamps to prevent leaks
• Inspect periodically for diaphragm cracking or leakage and replace when needed

Who is this for: This DASPARTS fuel pump is aimed at classic Volkswagen owners, restorers and mechanics who need a reliable, period-correct replacement for generator-era air-cooled engines. It is especially useful when maintaining originality on Beetle, Karmann Ghia, Bus and Type 3 vehicles from the 1950s through early 1970s, or when a worn pump is causing poor fuel flow or leaks. Choose this pump if you want a part that fits the OEM footprint and restores correct carbureted fuel delivery without aftermarket high-pressure conversion.
