Frequently Asked Questions

What is a fuel system priming pump used for?

A fuel system priming pump (like the J-47912) is used primarily on diesel engines after replacing fuel filters or lines. It manually pressurizes the fuel system to remove trapped air (bleeding) before starting the engine, preventing damage to the high-pressure injection components.

Can I use a low-pressure electric fuel pump on a fuel-injected engine?

No. Low-pressure electric fuel pumps (3-6 PSI) are only suitable for carbureted engines. Fuel-injected systems require much higher pressure, typically 40 PSI or more, and a high-flow pump to operate correctly.

Why is fuel stabilization important for replacement systems?

Fuel stabilization prevents gasoline from breaking down and creating corrosive sludge and varnish. This breakdown can clog new fuel lines, filters, and pumps, causing premature failure, especially in vehicles stored for extended periods.

What does the CP4.2 Inlet Metering Valve do?

The Inlet Metering Valve (IMV) controls the amount of fuel entering the high-pressure CP4.2 pump in diesel engines (like the Duramax LML). An improved replacement IMV helps regulate fuel flow more precisely, protecting the pump from excessive wear and potential failure.
