STANDPIPE WITH INTEGRATED REGULATOR VALVE |
摘要 |
An apparatus, system, and method for bypassing a fuel filter pressure regulation valve which includes a bypass window and bypass passage. The bypass passage window is positioned in the top of a standpipe of a filter. The filter includes a filter cartridge with top and bottom end plates. The top end plate of the filter cartridge has a hole to receive a standpipe. The top end plate also has a sealing gasket to seal the bypass passage window when the proper filter cartridge is in place. This arrangement exposes the regulator valve to the fuel and/or air at the top of the filter housing when the proper filter cartridge is in place. Pressure in the housing opens the valve, allowing air and/or fuel to be vented through the bypass passage and back to the fuel tank.
