I have a 2005 Lariat 2wd that is tripping the P0194 code. In troubleshooting this code, I have found that the vacuum hose that connects to the FRPS is disconnected and just dangling on the passenger side of the engine. I can not, for the life of me, find ANY pictures of where this is supposed to connect.

Can somebody please trace your vacuum hose off of the FRPS and take a picture of what it connects to?

Thanks in advance!

Sorry i can't go out and look because of the tropical storm right now . I don't recall a vacuum line on it . it has four wires and goes to fuel demand module above spare tire . And those units are troublesome-corrosion.
I do know this system does not return fuel to the tank it only pumps up when the sensor demand system says go .

Thanks red! I definitely see the fuel pressure sensor and see the vacuum tube coming off it but hopefully someone might be able to provide that picture so I can see where the other end of that vacuum tube ends up on that Tee you are talking about.

hard to get to there. There is an intake runner control back there that causes trouble . retunes intake for different loading of engine .
are you saying you want to chase this whole line back to vacuum source?
