G 30 Van V8-454 7.4L VIN N TBI (1995)
Modular Fuel Sender Assembly: Description and Operation
The fuel pump is a turbine type, low pressure electric pump, mounted in the fuel tank. Fuel is pumped at a positive pressure from the fuel pump through
the in-line filter to the pressure regulator in the TBI unit. Excess fuel is returned to the fuel tank through the fuel return line.
The fuel pump is attached to the fuel gage sender assembly. A fuel strainer is attached to the fuel pump inlet line and prevents dirt particles from entering
the fuel line and tends to separate water from the fuel.
Vapor lock problems are reduced when using an electric pump because the fuel is pushed from the tank under pressure rather than being pulled under
vacuum, a condition that produces vapor.
