Restored German Pierburg Fuel Pump Installation

Restored German Pierburg Fuel Pump Installation

If you've recently purchased one of our Restored German Pierburg Fuel Pumps, We'd like to first like to thank you for supporting a small business.

It's time to replace that incorrect aftermarket unit. Now that you've unpacked the box, you may be wondering, "how do I correctly install this gem?" As stated, these cars were designed to be worked on. (The Peoples Car) Let's get started.

Remove old pump

  1. Loosen the hose clamps and remove the fuel line (incoming and outgoing) from the old fuel pump. It helps to have a small rag handy to catch any fuel that may be left over in the line; not to worry. Note: On 1965 and earlier models, unscrew the inlet line with a line wrench.
  2. Now, remove the two nuts (13mm) that connect the pump to the engine. The rear bolt can be a bit tough. Once free, lift up the old fuel pump and remove.
  3. Lift the pushrod out, and inspect for wear. Be careful not to damage the flange. You will add some new grease as stated below.

Install new pump

  1. Place the new gaskets on the top and bottom of the flange. These shipped with your Restored German Fuel Pump. The flange should lift up.
  2. Apply some grease to the fuel pump pushrod and then slide it back down through the insulator block guide tube, with the pointed end down.
  3. Set the fuel pump in place over the studs, gasket, and insulating block and tighten it to the case with two 13mm nuts. Torque the nuts to to 18 ft-lb. Do not over-tighten.
  4. Now, reconnect the fuel lines - the rear inlet on the fuel pump comes from the fuel tank; the top inlet goes upward to the carburetor; tighten the hose clamps securely. On 1965 and earlier models, screw the inlet line into the fuel pump with a line wrench.
  5. Start your engine. Let it warm up to a smooth idle with your new pump installed. Please email us if you have any questions at all.
