Hello, can you give us the model of your van? It may not matter, with TBI, it is usually around 10 psi.
You'll have to tie into the supply line, if there isn't any schrader valve.

Fuel pressure 9-13 psi. If there is no schrader valve on the fuel line, I didn't see one, you need a tbi fuel pressure gage, tie-in the supply line at throttle-body. Be careful about pressure on the system.
