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
- 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.
- 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.
- 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
First; make sure you're using the correct 108mm generator style pushrod. Using an incorrect rod can break the pump and void your warranty.
- 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.
- 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.
- 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.
- 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.
- 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.
