Angry Where is schrader valve on fuel supply line?

OK...I know this is kinda lame, but, my 2000, F250 , 7.3 powerstroke is not living up to it's name. It,s running rough, stumbles and loses power when tank level drops to 1/4 or less. I thought I would check the fuel pressure but cant figure out where to hook up the gauge. I have a subscription to the AlldataDiy site for this truck and it shows a diagram of the fuel lines. It doesn't match my truck.

I dont have any schrader valve that I can see, let alone a "fuel rail". Just metal lines threading directly into each head from the fuel filter assembly.

Any ideas?:

Mine does the same thing. The fuel pickup tube in the gas tank is sucking air. Do a search for the Hutch mod, this will correct your problem. I havent done mine yet as I will be dropping the tank shortly for another project and plan to do it at the same time.

one thing to also think about , is gauge is possible to be reading off some, seen it before , maybe its about out and doesnt have as much in it as you think , but is a chance of the sending unit being clogged and bypassing the lower screen, and that will cause it also , i'd just take the tank out

Even a semi full tank sucks. I was changing the in tank fuel pump for a customer whose fuel gauge said empty. What the lady failed to tell me was the gauge didnt work. Damn near full tank of fuel landed flat on top of me. Good times
