1. A cleaning and pressure check device for placing the interior of a canister into fluid communication with an internal combustion engine via a fluid hose, the cleaning and pressure check device comprising:

  • a manifold body having first and second fluid ducts extending therethrough;

    a first coupling member attached to the manifold body, the fluid hose being releasably attachable to the first coupling member and placeable into fluid communication with the first fluid duct thereby;

    an elongate fluid tube attached to and extending from the manifold body, the fluid tube being fluidly connected to the first fluid duct;

    a pressure gauge attached to the manifold body and fluidly connected to the first fluid duct;

    a pressure regulator attached to the manifold body and fluidly connected to the second fluid duct, the pressure regulator being operable to selectively place the second fluid duct into fluid communication with at least one of a pressurized air source and ambient air;

    a shut-off valve disposed within the manifold body and operable to selectively block the flow of fluid between the fluid tube and the first coupling member; and

    a safety check valve disposed within the manifold body and operable to selectively block the flow of fluid through the second fluid duct;

    the manifold body being configured to permit the releasable attachment of the canister thereto in a manner wherein the fluid tube extends into the interior of the canister and the second fluid duct is in fluid communication therewith.
