It's under/inside intake manifold. You have a spider fuel injection system. TEst port should be seeen above intake mainfold behind what appears to be the carb. It will have a screw on cap which covers a shrader valve. Look like a tire air valve. Engine off, cap off, have rag in hand and depress valve - gas should squirt out if any pressure in system. Be careful with your eyes or hot exhaust manifold.
