95 Dakota Sport 4 cyl

can someone please tell me how to check the fuel pressure on this model. I bought a fule pressure gauge but there is no test post on the fuel line. It says in the book to connect it to the fuel inlet usuing a t-fitting on TBI models. Is this correct? if so where can i get this t-fitting that the book so briefly mentions

Most auto parts stores sell a fuel pressure test kit, that includes the gauge and various fittings and hoses for various applications. If you just bought at gauge, you didn't get a kit. Look for the complete package.
