Oil Pump Cover, with Full Flow Outlet Hole, for VW Aircooled

EMPI Full Flow Oil Pump Cover for VW Aircooled Engines

Product Overview

The EMPI Oil Pump Cover is an essential upgrade for Volkswagen enthusiasts looking to improve engine longevity through a full-flow oil system. This cover is manufactured from heavy-duty cast aluminum and features a pre-tapped 3/8" NPT threaded boss, designed specifically for routing oil to an external filter or cooler. It is engineered to fit VW oil pumps utilizing 8mm case studs and includes the required fitting and gasket to streamline your installation process.

Vehicle Fitment Guide

This cover is designed for 1300cc to 1600cc based engines. Please verify that your oil pump uses 8mm mounting bolts before purchase. This component fits the following models:

• VW Beetle (Standard): 19661979
• VW Bus / Type 2: 19631971
• VW Type 3 (Fastback, Notchback, Squareback): 19621973
• VW Thing: 19731974

Pro Tech Tips for Installation

Tip 1: Proper Thread Sealing. When installing the 3/8" NPT fitting into the cast aluminum cover, always use a dedicated thread sealant or Teflon tape to prevent leaks. Because NPT threads are tapered, do not over-tighten the fitting, as excessive force can crack the aluminum housing.

Tip 2: Verify Gear Clearance. Before final torque-down, ensure your oil pump gears are flush with the pump body. If the gears protrude slightly, they may rub against the aluminum cover, creating metal shavings. Use the included gasket to provide the necessary clearance and ensure a leak-free seal.

Tip 3: Understand the Full-Flow Loop. Installing this cover is the "outlet" for your oil. For a true full-flow system to work, you must also have a return port drilled and tapped into the engine case (typically near the oil pressure relief valve). Running this cover without a return line will result in immediate engine failure due to a lack of oil lubrication.
