Fuel Rail: Description and Operation
Fuel System View
FUEL SUPPLY LINE
The fuel supply line delivers fuel from a high pressure electric fuel pump (mounted in the fuel tank), to the in-line fuel accumulator and then from the
accumulator to the in-line fuel filter. It is then delivered to the fuel pressure regulator mounted on the fuel delivery pipe. The steel line is fitted in place
with threaded pressure fittings.
FUEL DELIVERY PIPE
The fuel delivery pipe, located on top of the engine, is a metal tube with threaded fittings which connects the fuel supply/return hoses, the fuel pressure
regulator and the fuel injectors. Its function is to deliver fuel to the injectors and help stabilize fuel pressure at the injectors.
FUEL RETURN LINE
The fuel return line routes fuel directly from the return outlet of the fuel pressure regulator to the return inlet on the fuel tank. The steel line is fitted in
place with conventional fuel hoses with clamps.
VAPOR RECOVERY LINE
The vapor recovery line delivers fuel vapors from the outlet on the fuel tank through the rollover valve (fuel check valve) to the charcoal vapor
recovery canister. The steel line is connected to the valve and the tank outlet with conventional fuel hoses and clamps. The remaining portion of the
line is vapor hose with clamps attaching it to the valve and the charcoal canister.
