DASPARTS Mechanical Fuel Pump for generator-era VW Beetle, Ghia & Bus — Direct-fit 113127025D

DASPARTS 113127025D is a mechanical fuel pump built as a direct-fit replacement for older Volkswagen air-cooled models, restoring correct fuel delivery to Beetle, Ghia and Bus engines produced through the early 1970s.

This aftermarket mechanical fuel pump reproduces the original form, fit and mounting of the OEM 113127025D style pumps used on classic VW air-cooled engines. It fits a wide range of Volkswagen KAEFER (Beetle) and Type 2 (Bus) applications and is designed for use with generator-equipped vehicles. The unit supplies the carburetor with consistent flow and pressure when installed and adjusted to factory specifications.

Which Volkswagen models and years will this pump fit?

This DASPARTS pump covers many air‑cooled VW models from the 1950s through the mid‑1970s. Fitment includes multiple Beetle body styles, Karmann Ghia, Type 3, and early Type II buses that used the generator setup rather than alternators.

• Beetle Sedan (1954–1977), Ragtop (1954–1963), Sunroof (1964–1977)
• Beetle Convertible (1954–1970) and Super Beetle Sedan (1971–1975)
• Karmann Ghia Coupe/Convertible (1956–1974)
• Type II Bus (1955–1979) and Type 3 Fastback/Squareback (1962–1973)

How does this pump match the original equipment and installation?

The 113127025D replacement mirrors OE mounting points, inlet/outlet locations and pushrod interface so it installs without case modifications on compatible engines. It’s intended for generator-equipped engines and is engineered to accept standard fuel lines and gaskets used on the original pumps.

• Direct-fit mounting bolt pattern and pushrod interface for generator-era VW engines
• Standard male inlet/outlet fittings for fuel hose clamps
• Works with existing gaskets and hardware from the original pump

What performance and durability should I expect?

The pump provides steady mechanical fuel delivery suitable for carbureted, naturally aspirated air‑cooled engines. While not an electronic pump, it’s built to withstand typical cruising and idling conditions of classic VW operation when installed correctly and periodically inspected.

• Consistent diaphragm-operated fuel delivery for carburetor needs
• Robust body and fittings compatible with common gasoline blends
• Easy serviceability—replace rather than repair for time-efficient maintenance

What should I check during installation and after fitment?

Proper installation ensures reliable operation: verify pushrod length, use a fresh gasket, and route fuel lines away from heat sources. After installation, inspect for leaks, confirm fuel pressure and check for smooth engine idle and throttle response.

• Use a new gasket and torque mounting bolts to factory specs
• Confirm pushrod engagement and valve timing are correct
• Test for fuel leaks and verify steady carburetor flow at idle and under load

Who this part is for: Restorers, DIY mechanics and vintage Volkswagen owners who need a faithful mechanical replacement for generator-era fuel systems will find the DASPARTS 113127025D pump useful. It’s aimed at people restoring authenticity and reliability to Beetles, Ghia coupes, Type 3s and early Type II buses where the original pump architecture is required. If you own a carbureted, air-cooled VW built within the listed years and want a straightforward, OEM-style replacement, this pump is a practical choice.
