Fuel Pressure Tap in for Lt1 Engine(camaro 93-97, Firebird 93-97, Corvette 92-97)

There is a little nob in the back of the engine that screws off. It looks like the nob that you would screw off and put air in a tire. You will need a Fuel pressure gauge. Once you have the cap off, you put your fuel pressure gauge on it and it screws right down. Then your done, all you need to do is to turn your car on and see your fuel pressure. Its hard to see but the first picture has a red arrow pointing to it. The second picture shows what it looks like. These pictures were taken off my 95 camaro z28
