Unsafe Condition
Due to high fuel pressure, caused by exceeding pressure in front of the mechanical fuel pump (e.g., due to an electrical fuel pump), in limited cases a deviation in the fuel supply could occur. This can result in exceeding of the fuel pressure and might cause engine malfunction and/or massive fuel leakage.
