Hey everyone, I have an 07 with 155k did oil pump, water pump, radiator, new time omg chain, cam phasers Ect... about 5k ago. Truck ran good for a min then began to lag when under a lid or accelerating. Thought it might be catalytic converters plugged but check them an there spotless. I am now checking fuel pump, filter, ect. Can’t find a shearer valve on fuel rails so was hoping someone on here has used the T adapter to test a 5.4 or a similar method to check fuel pump psi. Any input would be helpful.

I can check my fuel pressure at the fuel rail by using torque pro. Cost me $5 for the app, $20 for the Bluetooth OBD II adapter for the truck. I don't know about t fittings though, sorry.

Have you changed the spark plugs, fuel filter, or injectors?
