How do you change the fuel pump on a VW Beetle?
I go through the installation of the pump, and also a check of the fuel pressure. That was a big surprise! At 5psi, it was twice what the carburetor specs. VW says to add a gasket or two to raise the pump and thereby limit the rod throw to lower the pressure.

What should the fuel pressure be on a VW Beetle?
The Pressure doesn’t have to be exactly 2.8. It even could be a bit higher or a bit lower. The Official Manual calls for “about” 2.8 psi at 3400 RPMs. In that range, Fuel Pressure will not compromise the Float Valve (Needle Valve).
Why did my VW Beetle not start up?
The assumption—the Fuel Pump had suffered a “vapor lock”—even though the weather wasn’t even hot. Recently, Frank Salvitti talked to me about the “vapor lock” which temporarily put his car out of commission. He had driven a few miles, parked his Beetle and gone into the store to make his purchases. When he came out—the car would not start.
How do you lower the fuel pump pressure?
Lowering Fuel Pump Out-put Pressure: Here’s the theory: by raising the Fuel Pump, the Push Rod (113-127-307) which actuates it will not be able to push the Pump Lever as far. By extending the distance which the Push Rod must travel, Fuel Pressure will be reduced. How do we raise the Pump?
What causes a fuel pump leak in a classic car?
Fuel System Leaks. Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems found in classic cars that are between 30 and 60 years old.

How can I tell if my fuel pump is still working?
To perform this test, you should connect the test gauge to the metal output line using a spare piece of rubber fuel hose and a clamp. Once the connection is sealed, crank the engine over for 20 seconds. This will provide a full pressure reading, letting you know whether or not the pump is still in working order.
