연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A fuel system pressure tester for motorcycles adapted to be connected in-line with a fuel tank female fitting and a fuel line male fitting, has a fitting body, a first fitting for connection with the fuel tank fitting with an internal, normally closed valve, a second fitting for connection with the fuel line fitting, a pressure gauge, and a manually operated valve with a valve actuating element and a connection for a fuel hose. The fitting body has an internal passageway connecting the first fitting, the second fitting, the pressure gauge, and the manually operated valve. A method of testing a fuel system of the motorcycle involves connecting the pressure tester to the fuel tank by connecting the male tester fitting with the fuel tank female fitting, and connecting the female tester fitting with the fuel line male fitting, energizing the in-tank fuel sending unit, and reading pressure within the tester indicated by the pressure gauge.

1. A fuel system pressure tester for motorcycles adapted to be connected in-line with a fuel tank fitting which is one of a male fitting and a female fitting and a fuel line fitting, which is the other one of the male fitting and the female fitting, the fuel system pressure tester comprising: a fitting body forming an internal passageway,a first fitting affixed to the fitting body adapted for connection with the fuel tank fitting and communicating with the internal passageway,a first normally closed valve with a first valve member and a first valve seat arranged in the first fitting for preventing the flow of fuel through the first fitting when the first normally closed valve is in a closed condition and permitting the flow of fuel through the first fitting when the first normally closed valve is an open condition,a second fitting affixed to the fitting body adapted for connection with the fuel line fitting and communicating with the internal passageway,a second normally closed valve with a second valve member and a second valve seat arranged in the second fitting for preventing the flow of fuel through the second fitting when the second normally closed valve is in a closed condition and permitting the flow of fuel through the second fitting when the second normally closed valve is an open condition,a pressure gauge affixed to the fitting body and communicating with the internal passageway, anda manually operated valve affixed to the fitting body communicating with the internal passageway having a valve actuating element and a connection for a fuel hose, the manually operated valve allowing the flow of fuel between the internal passageway and the fuel hose when in an open condition, and preventing the flow of fuel between the internal passageway and the fuel hose when in a closed condition. 2. The fuel system pressure tester in accordance with claim 1, wherein the manually operated valve actuating element is a plunger element and the manually operated valve is normally in the closed condition and transitions to the open condition when the plunger element is operated. 3. The fuel system pressure tester in accordance with claim 1, further comprising a venting tool with a post having a sufficient length to move the second valve member of the second fitting from the second valve seat and to actuate the internal normally closed valve to the open condition. 4. The fuel system pressure tester in accordance with claim 3, wherein the venting tool is attached to the fitting body with a flexible strap. 5. The fuel system pressure tester in accordance with claim 1, wherein the first fitting is a female fitting and the second fitting is a male fitting. 6. A method of testing a fuel system of a motorcycle having a fuel tank with a tank female fitting, a fuel line with a fuel line male fitting, and an in-tank fuel sending unit, comprising the steps of: providing a pressure tester having a fitting body forming an internal passageway, a male fitting affixed to the fitting body adapted for connection with the fuel tank female fitting and communicating with the internal passageway, providing a first normally closed valve with a first valve member and a first valve seat arranged in the male tester fitting for preventing the flow of fuel through the male tester fitting when the first normally closed valve is in a closed condition and permitting the flow of fuel through the male tester fitting when the first normally closed valve is an open condition, providing a female tester fitting affixed to the fitting body adapted for connection with the fuel line male fitting and communicating with the internal passageway, providing a second normally closed valve with a second valve member and a second valve seat arranged in the female tester fitting for preventing the flow of fuel through the female fitting when the second normally closed valve is in a closed condition and permitting the flow of fuel through the female tester fitting when the second normally closed valve is an open condition, providing a pressure gauge affixed to the fitting body and communicating with the internal passageway, providing a manually operated valve affixed to the fitting body having a valve actuating element and a connection for a fuel hose, the manually operated valve allowing the flow of fuel between the internal passageway and the fuel hose when in an open condition, and preventing the flow of fuel between the internal passageway and the fuel hose when in a closed conditionconnecting the pressure tester to the fuel tank by connecting the male tester fitting with the fuel tank female fitting, and connecting the female tester fitting with the fuel line male fitting,energizing the in-tank fuel sending unit, andreading pressure within the tester internal passageway indicated by the pressure gauge. 7. The method of testing in accordance with claim 6, further comprising the step of relieving pressure in the pressure tester after reading the pressure by moving the first or second valve member to the open condition. 8. The method of testing in accordance with claim 6, further comprising the step of conducting a fuel pressure load test by inserting the fuel hose into a receptacle and reading the pressure step occurring while the valve actuating element is operated and causing a fuel flow through the pressure tester simulating a full-load operating condition of the motorcycle engine. 9. The method of testing in accordance with claim 8, wherein the receptacle is the fuel tank and the fuel hose is inserted through a fuel tank filler opening. 10. The method of testing in accordance with claim 6, further comprising the steps of providing a valve actuating element to move the first or second valve element to the open condition, deenergizing the in-tank fuel sending unit, inserting the fuel hose into a receptacle, operating the first or second valve element to the open condition, and releasing fuel through the fuel hose until atmospheric pressure prevails inside the fitting body internal passageway. 11. The method of testing in accordance with claim 6, further comprising the steps of disconnecting the pressure tester from the fuel tank by disconnecting the male tester fitting from the fuel tank female fitting, and by disconnecting the female tester fitting from the fuel line male fitting. 12. The method of testing in accordance with claim 11, further comprising the steps of inserting the fuel hose into a receptacle, inserting a venting post into the female fitting for opening the first internal valve, operating the valve actuating element, and allowing the fuel to drain from the fitting body through the fuel hose by gravitational force.
