Glacier Diesel Power Fuel Boss 1 PSI Check Valve (SKU FB-1PSI-CV)
This listing is the check valve only — a replacement one-way fuel check valve. It is not the Fuel Boss mechanical lift pump (FB-1000) and not a complete Fuel Boss kit.
Description
Genuine Glacier Diesel Power Fuel Boss 1 PSI check valve for Fuel Boss mechanical lift pump systems. It allows fuel to flow toward the engine and helps prevent reverse flow after shutdown so the Fuel Boss system stays primed and drain-back is reduced.
Cracking pressure is 1 PSI: low opening pressure with enough spring tension to limit reverse flow and restriction.
Features
- SKU FB-1PSI-CV — check valve only
- 1 PSI cracking pressure
- One-way fuel flow
- For Glacier Diesel Power Fuel Boss mechanical lift pump systems
- Compatible with Standard Drive and Hyper Drive Fuel Boss systems
- Helps maintain fuel system prime and reduce drain-back
- Compatible with diesel fuel / ULSD
Applications
Designed for use with Glacier Diesel Power Fuel Boss mechanical lift pump systems. Commonly used on Fuel Boss–equipped Dodge Ram 5.9L Cummins applications listed with the Fuel Boss system (including 1994–2007 ranges called out on the prior listing).
Important notes
- Install in the correct flow direction.
- Inspect for contamination, sticking, or damage whenever the Fuel Boss system is serviced; replace if needed.
- Related part sold separately: Fuel Boss Replacement Mechanical Pump (FB-1000). Do not confuse with this check-valve SKU.
