If you have low fuel supply pressure and know the supply pump is good, a bad overflow valve can cause low supply pressure. It can also contribute to a hard start issue. Valve is located on the Injection pump, connecting the banjo fitting return line to the tank.

What does it do?

The overflow valve regulates the fuel circulating throughout the engine to maintain proper fuel pressure for the engine to operate. The valve is key to ensuring that the engine has the proper power to function as it maintains balanced low fuel pressure in the pump.

Purpose

• Balances low pressure in the fuel pump
• Regulates the fuel pressure on the high-pressure pump
• Prevents excessive pressure on the fuel line and pump
• Maintains fuel pressure in the pump
• Sends unused fuel from the high-pressure fuel line back to the fuel tank
• Efficient fuel pump operation
• Cost-effective maintenance

SIGNS OF NEEDING REPLACEMENT

• Low or high fuel pressure
• Seized valve
• Fuel leakage
• Engine has low power
• Engine won't start

CAUSES OF FAILURE

• Mechanical failure
• Contaminated fuel
• Improper installation
• Poor maintenance practices
• Normal wear and age
