40 HP - Pierburg Fuel Pump

Ships from our workshop Decatur, Georgia, USA.
2 items left

Each restored German Pierburg Fuel Pump is first disassembled and inspected for viability in our workshop. Once it passes this test, it is thoroughly cleaned inside and out. During restoration, each pump is fitted with brand new, custom-crafted superior quality diaphragms, (Effbe, which is the OEM supplier to VW) that are formulated with nitrile rubber to withstand modern gasoline blended with ethanol.

Our pumps are a work of art, and as beautiful on the inside as they are on the outside.

Which pump is period correct for my Vintage VW?
1300/1600 - 1966 - 1979 VWs
40HP - 1960 - 1965 VWs
*36HP - 1953 - 1960 VWs
25HP - 1952 - 1953 VWs

We can also correctly restore any fuel pump, if you'd like to ship yours to our workshop. Contact us, if interested.

About fuel pressure
Original factory manuals specify a fuel pressure of approximately 1.30 to 1.87 pounds per square inch (psi) for 25hp and 36hp pumps through 1958. After this time, pressure specifications were increased to a maximum of approximately 2.5psi. This pressure rating was retained through 36hp engine production and continued on 40hp and the later 1300/1500 engines.

Although the preload on the diaphragms is designed to set the fuel pressure within the specified range, we recommend you check the pressure with a gauge after you install the pump in your engine.  If you find the pressure too great, you can reduce it by adding another gasket between the pump and base or between the pump base and case.
