Abstract
A 'no filter, no run' filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.
