Glacier Diesel Power Fuel Boss 1 PSI Check Valve | Replacement One-Way Fuel Check Valve
Description
Restore proper fuel system operation with a genuine Glacier Diesel Power Fuel Boss 1 PSI Check Valve.
This replacement one-way check valve is engineered specifically for Glacier Diesel Power Fuel Boss mechanical lift pump systems. Its purpose is simple but critical—it allows fuel to flow toward the engine while preventing it from flowing backward once the engine is shut off. This helps keep the Fuel Boss system primed, minimizes drain-back, and promotes faster starts after the vehicle has been sitting.
The valve features a 1 PSI cracking pressure, meaning it opens with very little fuel pressure while still providing enough spring tension to prevent reverse flow. This low opening pressure minimizes restriction while maintaining dependable fuel system performance.
Whether you're replacing a worn check valve or rebuilding your Fuel Boss system, installing a genuine Glacier Diesel Power replacement helps ensure your mechanical lift pump continues delivering reliable fuel pressure every time you turn the key.

- Direct replacement component for existing Fuel Boss systems
Why a Check Valve Is Important
A check valve is a one-way valve that allows fuel to travel in only one direction.
When the engine is running, fuel flows freely through the valve toward the injection system.
After the engine is shut off, the valve closes to help prevent fuel from flowing backward through the system.
This provides several important benefits:
- Helps keep the fuel system primed
- Reduces drain-back after shutdown
- Helps minimize air entering the fuel system
- Shortens restart time after extended parking
- Promotes more consistent fuel delivery
Although small, the check valve plays an important role in maintaining reliable operation of the entire Fuel Boss system.
Glacier Tech Tip
Many fuel system issues that appear to be pump problems are actually caused by air entering the fuel system.
If fuel drains backward after shutdown, the lift pump must refill portions of the system before normal fuel pressure can be restored. This can lead to extended crank times, inconsistent fuel pressure during startup, or intermittent air bubbles within the fuel system.
A properly functioning check valve helps retain fuel inside the system after shutdown, reducing the amount of air that can enter during long periods of sitting. It's an inexpensive component that can have a noticeable impact on starting performance and overall fuel system consistency.
Whenever the Fuel Boss system is serviced, inspect the check valve for contamination, debris, or damage before reinstalling it.
Why Choose Genuine Glacier Diesel Power Components?
Fuel Boss systems are engineered as a complete fuel delivery package.
Every genuine Glacier Diesel Power replacement component is selected to work with the system's fuel pressure, flow requirements, and plumbing configuration.
The genuine Fuel Boss check valve provides:
- Correct 1 PSI opening pressure
- Reliable one-way sealing
- Proper flow characteristics
- Direct compatibility with Fuel Boss plumbing
- Proven long-term reliability
Using the correct replacement valve helps maintain the performance the Fuel Boss system was designed to deliver.
Applications
Designed for use with:
- Glacier Diesel Power Fuel Boss Mechanical Lift Pump Systems
Compatible with:
- Standard Drive Fuel Boss systems
- Hyper Drive Fuel Boss systems
Commonly used on:
- 1994–1998 Dodge Ram 5.9L Cummins
- 1998.5–2002 Dodge Ram 5.9L Cummins
- 2003–2004.5 Dodge Ram 5.9L Cummins
- 2005–2007 Dodge Ram 5.9L Cummins equipped with a Fuel Boss system.
Important Notes
- Genuine Glacier Diesel Power replacement part.
- Designed specifically for Fuel Boss mechanical lift pump systems.
- 1 PSI cracking pressure.
- One-way valve—install in the correct flow direction.
- Inspect fuel lines and fittings whenever servicing the check valve.
- Replace if contamination, sticking, or physical damage is found.
Common Failure Point
Check valves are designed for long service life, but contamination from dirty fuel or debris can prevent the internal sealing mechanism from closing completely.
Signs of a worn or contaminated check valve may include:
- Extended crank times after sitting overnight
- Fuel draining back toward the tank
- Loss of fuel prime
- Air entering the fuel system
- Inconsistent fuel pressure immediately after startup
Before replacing the check valve, inspect the Fuel Boss filters, fuel hoses, fittings, and pump drive system to ensure no other issues are contributing to the problem.
Complete Your Fuel Boss System
Keep your Fuel Boss operating at peak performance with genuine Glacier Diesel Power replacement components:
- Fuel Boss Replacement Mechanical Pump (FB-1000)
- Fuel Boss Replacement Belts (56T, 58T & 60T)
- Fuel Boss Fuel Filter Elements
- Fuel Boss Hyper Drive Upgrade Kit
- Fuel Pressure Test Kit
