During normal operation air from the crankcase will exert a force on the plunger. This eliminates excess fuel that would otherwise be forced through the fuel line due to pressure in the tank, and avoids the related flooding and engine failure. The fuel is typically delivered to the engine via a fuel line. Parts, Rule 1500 GPH Automatic Racks, Fish Finders, Sounders Fishing Lures, Fishing Rod Holders & PCV Valves work by using a simple force balance on the plunger.

A pair of one-way valves inside the pump only allow the gas to move in one direction (toward the engine). Prior to the change, fuel tanks were manufactured with a fuel filler cap that vented and released gas vapor into the atmosphere. The upstream pressure is a differential pressure between the inlet and outlet and is referred to as the check valve cracking pressure. Platforms, Slide As a result, one tank keeps working and the other does not. How does a carburetor work 4 stroke? So you can either choose to get sprayed in the face with gas, cause a fine-worthy spill, or vent the tank manually before connecting it, defeating the whole purpose of it's misguided design.
