1975 and Later Beetle and Super Beetles were equipped with Bosch Fuel Injection from the factory. The fuel injection, as simple as it is, works well when everything is set up properly and in good working order. Unfortunately there aren't many people on the planet that know how to diagnose and fix any problems that can come up. For that reason, many people choose to swap out the original fuel injection system for a carburetor. Our Fuel Injection to Carburetor Conversion Kit includes just about everything needed to swap your factory fuel injection out to carburetor. From an air cleaner and carburetor, to the manifold, boots, clamps, end castings and gaskets, and alternator stand. The kit requires a good working knowledge of simple VW mechanics. A 1973 and earlier style exhaust system with heat risers is recommended (more so a necessity) to hook up to the intake manifold and prevent it from icing up.

Kit Includes:
-113129031KJB Replacement 34PICT3 Carburetor with Air Cleaner, Barrel Nut, Base Gasket & Throttle Cable Extender
-Dual Port Intake Manifold, End Castings, Boots, Clamps and Gaskets
-Alternator Stand, Deflect Plate & Oil Filler with Breather Hose
-Low Pressure Electric Fuel Pump, Fittings, Fuel Line & Clamps

The Fuel Injection to Carb kit consists of the stock 1971 through 1974 Beetle components so the kit will fit all Type 1 based, Dual Port engines.

Installing a Carburetor on an emission controlled car may not be legal in your area! Check with your local DMV for smog laws concerning such a swap before ordering.


An exhaust system with heat risers is highly recommended to hook up to the new dual port intake manifold.

Swapping to an 1973 and earlier exhaust system requires new heater boxes or J-tubes as the original heater boxes and intermediate pipes are not compatible with the earlier exhaust systems.

Intake Manifold Trimming Recommendations:

Due to manufacturing variances and the supplier wanting to either fit all possible stroker engine combinations, or simply not checking the reproduction manifold versus a stock manifold, the tubes on the intake manifolds and the heat riser will have to be trimmed to length before installation. Regardless, there are currently no other new alternatives for a new stock replacement intake manifold.

32mm (1 1/4") off the 3-4 (left) side intake tube
48mm (1 7/8") off the 3-4 (left) side heat riser tube

We whole heartedly wish this wasn't the case but until the supplier runs through their incorrect stock or demands a better product, this is what is available to the industry. We are working as hard as possible to find another solution but for now trimming is required. We use a pipe cutter (the intake tube is 1 3/8" diameter) for the cleanest cut, but you can use a sawzall, hack saw, cut off wheel, etc.

Make sure you check the fitment before trimming! The cross tube from end casting to end casting should be measure roughly 16.75" to 17.75" across. The variation being that the intake manifold can and should slightly enter into each end casting.

Fuel Injection to Carburetor Conversion


Installing the carburetor conversion kit is an involved process but we have put together a brief list of the steps and instructions to converting your Beetle from fuel injection to carburetor.

The installation begins with disconnecting the battery as various engine wires will be disconnected. From there all of the factory fuel injection components need to be removed. This includes the air box and breather hoses, air flow meter, throttle body, intake manifold, end castings (with fuel injectors), etc. The fuel hoses and wiring in the engine compartment connecting to the fuel injection components need to be disconnected and removed as well. The alternator needs to be unstrapped from the stand and the fuel injected intake manifold and alternator stand can be removed.

With the majority of the upper engine components removed you can pull the accelerator cable from the fan shroud, and remove the fan shroud to drill the new guide hole for the accelerator cable. Or you can install a new (or used) doghouse fan shroud that is already drilled for the carburetor cable.

Install the oil deflect plate and new alternator stand. With the new stand in place, strap the alternator down to the stand. The new oil filler tube can be screwed into the new stand as well. The drilled, new or used fan shroud and alternator can now be set in placed (while guiding the accelerator cable through) and the alternator can be strapped in place.

The new intake manifold now slides in place and the boots and clamps slide in place on either side. Install one of the intake end castings (after installing new gaskets at both heads) and slide the manifold and boot in place. Repeat the process for the opposite side intake end casting. Note that the intake manifold has heat risers (not installed) but unless you change your factory exhaust, they will not be hooked up. In warmer climates this isn't a major issue. In colder climates we highly recommend swapping the complete exhaust to a carbureted style (which is a good idea regardless of climate). If you have already swapped to a carbureted style muffler or exhaust install the heat risers in to the manifold and bolt them to the heat risers on the exhaust after installing new gaskets at the exhaust. With everything installed on the intake manifold in place tighten all of the nuts, bolts and manifold boot clamps.

Now install the new carburetor base gasket followed by the carburetor and tighten the mounting nuts. Install the fuel line at the carburetor and clamp it in place. Route the opposite end of the the left side of the engine and connect the hose to the original fuel hose or line. Then install the air filter and breather hose, the breather hose will route from the vent port on the bottom of the air cleaner to the vent port on the oil filler. Attach the re-routed accelerator cable to the carburetor linkage. Run a power wire from the positive side of the coil, to the idle solenoid on the carburetor, then to the choke element. This coil circuit is not fused so make sure the wire is routed away from any possible shorts.

The majority of the conversion is complete with the exception of the fuel system. The fuel injection system uses a relay that is controlled by the fuel injection computer to send power to the fuel pump. The relay, computer and pump need to be removed. The fuel return lines from the engine at the fuel pressure regulator back to the tank can be removed or capped off. Most importantly, cap off or plug the return line at the fuel tank.

The original fuel line from the tank to the pump can be re-used and installed at the inlet of the new fuel filter. Use a small section of hose to connect the filter to the inlet of the new electric fuel pump, then connect the original line to the new fuel pump outlet. Make sure the fuel pump is mounted securely to the chassis. The black wire is the ground wire for the pump and it can be grounded at the chassis mount. Power to the fuel pump can be sourced from any "key" hot fuse on the fuse box. The pump typically uses less than 5 amps of power.

At this point the installation is now complete, hook up the battery, turn on the key to ensure the fuel pump is working. Then check for and repair and fuel leaks. Start the car and double check the ignition timing and adjust (or have a mechanic adjust) the carburetor as needed.
