Product Description

EMPI's Single 44HPMX Carburetor Kit offers the performance of the two barrel HPMX carburetor and the ease of only having one carburetor. The 44HPMX carb is completely tuneable with air and fuel metering all being adjustable and the butterflies are drilled to help maintain a smooth idle. The carburetor kit includes the 44HPMX carburetor with linkage kit, a chrome air cleaner assembly with gauze filter, chrome velocity stacks, the isolated plenum center intake manifold (for use with single or dual port end castings), fuel line and mounting hardware. The single, two barrel carburetor kit fits Type 1 1300-1600 based engines. We recommend the single 44HPMX carburetor for displacements up to 1800cc. The carburetors are test run and adjusted for smooth performance out of the box. Fits 1966-1974 Beetle and Super Beetle. Will fit in 1963-1971 Bus and 1973-1974 Things if the idle jet vent tubes and velocity stacks are removed and a smaller air filter (8805) is used.

EMPI's 44HPMX Carburetor kits include:

  • Chrome Velocity Stacks
  • Air Craft Style Heim Joint Linkage
  • Isolated Plenum Aluminum Intake Manifold (fits single or dual port end castings)
  • Chrome Air Filter with High Flow Gauze Element
  • Mounting Hardware, Gaskets & Instructions

EMPI's 44HPMX Carburetor comes with the following parts installed:

  • 0.60 Idle Jets
  • .140 Main Jets
  • .160 Air Correction Jets
  • .350 Exhaust Pump Valve Jets
  • 0.55 Accelerator Pump Jets
  • F-11 Emulsion Tube
  • 30mm Venturis

What size carburetors do I need?

In general we use 40mm single carburetors for engines up to 1800ccs. 44mm carbs are used for 1800cc and larger engines. Cams, heads, valve sizes and other factors will determine which carburetor set up works best. At the end of the day though, when in doubt, go larger as venturis and jets can all be changed to make a larger carb suit a smaller engine as needed.

Why choose an EMPI HPMX carburetor over a Weber IDF?

Don't get us wrong, we're suckers for performance and when it comes to VW engines and performance carburetors, few will argue with the quality and performance that comes with the Weber name. That being said, there are better Weber versions than others with the Italian versions being the more preferred. So when EMPI decided to take on the task of reproducing one of the most popular VW performance carburetors they went to the best and made it better. They started with a 44 IDF carburetor as a base for the casting for both the 40HMPX and the 44HPMX carburetors. Some of the first improvements was updated circuitry and profiled throttle shafts to flow better right out of the box compared to the Weber. Now on their 4th generation, having made improvements along the way the HMPX carbs now feature a cast in enrichment plate block off, a vacuum port and extended idle jet tubes to help eliminate clogged idle jets. So, why choose an HPMX Carburetor? Because it works just as well, if not better than a IDF carburetor, it's less expensive, and all the components, jets, gaskets and parts are all interchangeable with the IDF. Why pay more for less?!

We ONLY ship within the United States and its territories.

Orders over $100 will receive free shipping within the continental United States. Freight on under $100 will be $9.95. Large packages ship FedEx. Smaller packages ship US Priority Mail. Delivery time averages 1-5 business days after it ships.

Most orders to Hawaii, Alaska, APO/FPO, Puerto Rico and other US territories are shipped by the US Postal Service. The shipping costs for these orders are billed at the time of shipping.

For expedited shipping, you must call us. All express orders are personally handled by the representative you speak with in order to streamline the process. Please do not request express shipping via email. Emails are reviewed in the order they are received which could possibly delay your shipping.

Shipping on any returns is the customer's responsibility. If your order qualified for free shipping and a returned item reduces your order below the $100, you will be charged the according shipping cost for the order.


90 Day Return Policy

You can return most unused, never installed, like-new items for 90 days from the date of receipt. Items must be in like-new condition. The following items are final sale:
  • Special order items
  • Special order upholstery
  • Electrical items
  • Installed carburetors
Like-new Condition: JBugs may refuse a return when the returned item is not in like-new condition. These situations will lead to refused returns:
  • Installed items
  • Items missing parts or the original packaging material
  • Items damaged in return shipping due to improper packaging
  • Carburetors that smell like fuel
  • Damage due to customer negligence
  • Items with scour marks that show installation or attempted installation from nuts, bolts, screw-driver’s, washers, etc.

Returns must be sent in a proper shipping box.
With the exception of parts that are shipped to you in the original manufacturer packaging (example - TMI door panels, floor pans, complete front beams, etc), please be sure to return the parts with an external box or protective packaging around the parts you are returning. Most manufacturer packaging boxes are not rated for shipping and can become damaged or destroyed as they are too thin to withstand forces applied during the shipping process. Failure to do so will result in a higher restocking/reboxing fee or outright refusal of the return if the part cannot be restocked in the same condition it arrived at you.
