Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
121 words
A kit for cleaning fuel injectors in a plurality of different motor vehicles comprising: a pressurized container of a mixture of a cleaning fluid and a fuel for said motor vehicle; a pressure regulator; at least a first coupling means for coupling said pressure regulator to said pressurized container; second coupling means for coupling an outlet of said pressure regulator to said fuel injectors; said second coupling means including at least first and second different adapters for coupling to said fuel injectors in respective ones of said different motor vehicles; and said pressure regulator including controllable means for regulating a pressure of said mixture at said outlet to a value appropriate for a particular motor vehicle to which it is coupled.
Claim 2
Dependent Claim
121 words

Claim 5
Dependent Claim
70 words
A kit according to claim 1, further comprising: an instruction manual; said instruction manual including instructions for selecting and assembling a selected fuel injector cleaner assembly from contents of said kit; said instruction manual further including instructions for coupling said selected fuel injector cleaner assembly to said motor vehicle; and said instruction manual further including instructions for selecting and controlling said pressure to a value appropriate for said motor vehicle.
Claim 6
Dependent Claim
82 words
A kit according to claim 4, wherein: said second coupling means includes at least first and second hoses; said at least first and second adapters including means for adapting said first and second hoses for attachment to different motor vehicles; said first hose having a first color; said second hose having a second color; and said instruction manual relating said first and second colors to first and second different motor vehicles whereby selection of said selected fuel injector cleaner assembly is simplified.
Claim 7
Dependent Claim
121 words
A kit for cleaning fuel injectors in at least first and second different motor vehicles, comprising: a pressurized container; a pressurized mixture of a cleaning fluid and a fuel in said pressurized container; a pressure regulator; first coupling means for coupling said mixture to said pressure regulator; second coupling means for coupling said pressure regulator to one of said at least first and second different motor vehicles; said second coupling means including at least first and second hoses and at least first and second adapters; and said pressure regulator including adjustable means for regulating a pressure of said mixture fed to said motor vehicle to a value appropriate for said one of said at least first and second different motor vehicles.
Claim 8
Dependent Claim
121 words
A kit for cleaning fuel injectors in at least first and second different motor vehicles, comprising: a pressurized container; a pressurized mixture of a cleaning fluid and a fuel in said pressurized container; a pressure regulator; first coupling means for coupling said mixture to said pressure regulator; second coupling means for coupling said pressure regulator to one of said at least first and second different motor vehicles; said second coupling means including at least first and second hoses and at least first and second adapters; and said pressure regulator including adjustable means for regulating a pressure of said mixture fed to said motor vehicle to a value appropriate for said one of said at least first and second different motor vehicles.
