A fuel supply arrangement

摘要

A fuel delivery arrangement for a fuel injected engine 12 has a single fuel line 16 extending from an in-tank fuel pump 14 to a fuel rail 18. Included within the fuel line 16 is a check valve 24 which allows fuel flow from the tank to the fuel rail but which prevents return flow while allowing any trapped fuel between the fuel rail and the check valve to expand to reduce pressure.
