Abstract

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.

Dependent claims

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, and
a 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.
