Cam follower high pressure fuel pump. Porsche 957 / 958 Cayenne 3.6L  ❭  95511030100

High Pressure Fuel Pump Cam Follower / Tappet
The Porsche Genuine OE Cam Follower / Tappet (Part No. 95511030100) is a precision-engineered internal engine component used within the high-pressure fuel pump system on Porsche engines. This part sits between the camshaft and the high-pressure fuel pump, acting as a contact interface that transfers motion from the camshaft to the fuel pump.

Fits:
Porsche 957 Cayenne 3.6L 2007 - 2010
Porsche 958 Cayenne 3.6L 2011 - 2018

Diagram ref no 18

The cam follower converts the rotational movement of the camshaft into linear motion, driving the high-pressure fuel pump. This enables the pump to generate the fuel pressure required for direct fuel injection systems.

It acts as a wear interface, protecting both the camshaft and fuel pump components from direct metal-to-metal contact.

Functions & Technical Role
•  Motion transfer: Converts camshaft rotation into fuel pump actuation
•  Fuel pressure support: Enables proper operation of the high-pressure fuel pump
•  Wear protection: Reduces direct contact between camshaft and pump
•  High-load durability: Designed to withstand constant friction and pressure
•  OEM precision: Manufactured to Porsche specifications for exact fit and reliability

Fitment / Position on car
•  Fitting position: Engine – cylinder head / fuel system
•  Location: Between the camshaft lobe and high-pressure fuel pump
•  System: High-pressure fuel delivery / direct injection system

Cam followers are subject to constant mechanical contact and high loads, making them a wear item over time. A worn or damaged follower can lead to:
•  Reduced fuel pressure and poor engine performance
•  Excessive wear on the camshaft or fuel pump
•  Engine noise or ticking Potential fuel system failure

Replacing with a genuine Porsche OE component ensures proper operation, protects critical engine parts, and maintains long-term reliability.
