Vacuum assisted regulator maintains pressure at injectors by allowing excess fuel to return to tank via return line.

Powertrain Control Module (PCM) controls fuel flow through injectors by varying injector pulse width.

Vehicle operates on unleaded gasoline (minimum posted octane rating of 87), or a mixture of unleaded gasoline (minimum posted octane rating of 87), and up to 85% methanol. (Never attempt to operate vehicle on 100 % methanol fuel.)

CONSTRUCTION

Fuel Delivery system consists of fuel tank, fuel pump, fuel filter, fuel rail, fuel injectors (4), and fuel pressure regulator.
