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.

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.
