ABSTRACT:
In a motorcar having a compressed fuel cylinder charged with a compressed fuel disposed in a compartment, pipes connected to the fuel cylinder within the compartment are connected to a joint unit penetrating a partition wall partitioning the compartment from an outside and the joint unit is connected to pipes connected to an internal combustion engine and the like out of the compartment. A fuel charge passage, a fuel supply passage and a relief passage in a cylinder cap of the fuel cylinder and a fuel charge passage, a fuel supply passage and a relief passage in an interior side of the joint unit are connected with each other through an interior charge pipe, and interior supply pipe and an interior fuel relief pipe, respectively. A fuel charge pipe, a fuel supply pipe and a relief pipe out of the compartment are connected to a fuel charge passage, a fuel supply passage and a relief passage in an exterior side of the joint unit. The interior fuel charge pipe, the interior fuel supply pipe and the interior fuel relief pipe are covered by a seal cover airtightly. A fuel leakage inspection is conducted by comparing gas pressures at two different times after fuel charging in the piping outside the compartment.
