Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pressure Test
For specifications see " FUEL PUMP PRESSURE AND VOLUME " in appropriate TUNE-UP story.
Some pumps have an internal bleed which lets pressure drop to zero with engine off.
Connect pressure gauge in fuel line at carburetor using a "T" fitting so carburetor will be supplied with fuel. Hose to gauge should have a second "T" and a valve, for venting and capacity test. Crank or run engine at specified RPM and open vent valve to release air in pump. Close vent and read pressure.
