A method for providing a fuel line gasket to an electromotive diesel fuel injector wherein the electromotive diesel fuel injector includes a nut defining a nut fuel line passageway that is in fluid communication with a fuel line having a fuel line passageway, the fuel line having a fuel line surface and the nut having a nut surface, said fuel line surface and said nut surface sealing by contacting each other, and wherein the fuel line gasket includes a body having two opposite interface surfaces with a hole defined within the interface surfaces, at least a portion of said body adapted to be positioned between the fuel line surface and the nut fuel surface, said method comprising the steps of:
- a) moving the nut away from the fuel line;
- b) positioning the gasket between the fuel line surface and the nut surface so that the opposites interface surfaces contact the fuel line surface and the nut surface, respectively;
- and
- c) compressing the gasket between the fuel line surface and the nut surface so that the interface surfaces contact respective ones of the fuel line surface and the nut surface and a liquid seal is formed there between so that fuel can pass through the fuel line passageway, the nut fuel line passageway and the hole defined in the body.
A fuel line gasket for use with an electromotive diesel fuel injector that includes a nut defining a nut fuel line passageway that is in fluid communication with a fuel line having a fuel line passageway, the fuel line having a fuel line surface and the nut having a nut surface, said fuel line gasket, comprising:
- a body having two opposite interface surfaces and a hole positioned within said interface surfaces, at least a portion of said body adapted to be positioned between the fuel line surface and the nut surface, so that said interface surfaces contact respective ones of the fuel line surface and the nut surface, and when said portion of said body is compressed between the fuel line surface and the nut surface, a liquid seal is formed and fuel can pass through the fuel line passageway, the nut fuel line passageway and through the hole defined in said body.
In an electromotive diesel fuel injector that includes a nut defining a nut fuel line passageway that is in fluid communication with a fuel line having a fuel line passageway, the fuel line having a fuel line surface and the nut having a nut surface, the improvement comprising a fuel line gasket positioned between the fuel line surface and the nut surface, said gasket comprising:
- a body having two opposite interface surfaces and a hole positioned within the interface surfaces, at least a portion of said body positioned between the fuel line surface and the nut surface, so that said interface surfaces contact respective ones of the fuel line surface and the nut surface, wherein at least a portion of said body is compressed between the fuel line surface and the nut surface, a liquid seal is formed and fuel can pass through the fuel line passageway, the nut fuel line passageway and through the hole defined in said body.
