Dependent claims

A dispenser for providing a chemical engine valve cleaner, the dispenser comprising, an external housing having a fluid outlet engaged with a flexible elongate delivery conduit, wherein the flexible elongate delivery conduit is wrapped around a portion of the external housing during storage, and during operation extends for a length of at least approximately 10 feet from the fluid outlet, and a fluid delivery end of the flexible elongate delivery conduit is supported for dispensing fluid to an engine intake manifold engaged with a support clip.

A method for cleaning vehicle engine intake valves, comprising the steps of:

unwrapping a flexible elongate delivery conduit from a storage position wrapped around a portion of a dispenser external housing connected with the flexible elongate delivery conduit at a fluid outlet in fluid communication with a canister of vehicle engine valve chemical cleaner,
attaching a support clip on a fluid delivery end of the flexible elongate delivery conduit;
clipping the support clip and fluid delivery end of the flexible elongate delivery conduit under an open hood of a vehicle to a vehicle engine intake manifold having vehicle engine intake valves to be cleaned;
extending the flexible elongate delivery conduit for a length of at least approximately 7 feet, together with the canister of vehicle engine valve chemical cleaner, to a driver seat location within a vehicle passenger compartment of the vehicle with the vehicle engine intake valves to be cleaned,
positioning the canister of vehicle engine valve chemical cleaner in one hand of a user seated in the driver seat location within the vehicle passenger compartment of the vehicle with the vehicle engine intake valves to be cleaned;
starting the vehicle engine using a second hand of the user seated in the driver seat location within the vehicle passenger compartment of the vehicle with the vehicle engine intake valves to be cleaned;
revving the vehicle engine to at least at least 2000-3500 RPM;
dispensing vehicle engine valve chemical cleaner into the vehicle engine by the user seated in the driver seat location within the vehicle passenger compartment of the vehicle with the vehicle engine intake valves to be cleaned activating a trigger on the dispenser external housing in fluid communication with the canister of vehicle engine valve chemical cleaner to spray vehicle engine valve chemical cleaner via the fluid delivery end of the flexible elongate delivery conduit supported by the support clip into the vehicle engine;
and
ceasing activation of the trigger and ceasing revving of the vehicle engine by the user seated in the driver seat location within the vehicle passenger compartment of the vehicle with the vehicle engine intake valves to be cleaned once the canister of vehicle engine valve chemical cleaner is empty.
