I have a 97 f250 power stroke. Does anyone know where I could get a fuel diagram that marks what all of the parts are? It has a mechanical pump just behind the fuel canister but I think there should be another pump somewhere else. Please help. This is my first diesel.

 

The pump behind the fuel canister is the only pump on the truck. I'm sure some others will be around to give you more info.

X2 that's the only one.

 

How do you check fuel pressure when it is a mechanical pump. I already know that it holds average fuel pressure while it is running. As it seems to starve itself and die the pressure goes down. It has a new fuel pump and fuel filter. The only way I can get it do run is by removing what I think is the main fuel line to atmosphere. When the fuel squirts out I can reconnect it and it will start right up and only run for a few minutes. At that time it is running rough. Do I have air in the system?

 

look on the driver side of the fuel bowl you will see the FPR(fuel pressure regulatior) bolted to the side of the fuel bowl at the bottom of the FPR you wiil see a black cap that covers what looks like the vavle stem on a tire use a stick style tire gauge and check with the truck running or with someone turning it over you need atleast 25psi to run but you want 60to70psi.

 

Just for grins .. .. remove the gas caps on the filler necks and see if it runs.

 

Thanks I will try that tomorrow. I will let you know. What about air in the system?

 

what Hussler is talking about is a bad gas cap not letting the tank breath and building a vacuum in the tank and cutting your fuel off.

 

From what you are describing I would think YES. But if you could post a picture of the actual "what I think is the main fuel line to atmosphere" hose that would be very helpful also.

 

WELCOME to the forum
I have this for you, maybe helps you:

 

Jose, my friend, that is a great diagram, I saved it for future reference.
Tried to rep ya but system won't let me.

 

Thanks Jim, I know about the system, dont worry.

 

THANK YOU! I am going to start integrating my transfer tank in to the fuel system tomorrow. That diagram is going to make my life much easier.
