Pangor Cycles 3-Bolt Manifold Pressure Tester for 1936-1948 Harley-Davidson Big Twin

Pangor Cycles 3-Bolt Manifold Pressure Tester for 1936-1948 Harley-Davidson Big Twin

Intake manifold leaks cause all manner of running problems—"hanging" idle, hard- or no-start conditions, difficult tuning, and in extreme scenarios, burnt valves and pistons.

• Runs with regular low-pressure air through a Schrader valve
• Stainless steel for years of service
• Open-foot chuck and low-pressure regulator required for use
• Gasket included
• Made in USA

The definitive test for intake manifold leaks is by placing the manifold under pressure or vacuum. Simply remove your carburetor and install this test tool with the included gasket. Apply constant, regulated air pressure of 10-15 PSI from an open air chuck, and spray the manifold with leak detection fluid or plain old soapy water. If you've got leaks, you'll see them. The bubbles don't lie!
