ABSTRACT:
A fuel feeding system for an LPI engine is made to allow fuel remaining inside a fuel supply line and a fuel return line to be drained into a bombe by bypassing a pressure regulator while an engine gets cooler after operation, whereby the fuel can be saved from external leakage via a fuel injector, and contaminants are reduced while the engine is running, resulting in improved maintenance of the engine during an engine overhaul.
