OK so I've had a slew of issues lately.. mostly with my Cat which have left me puzzled. Ive had to bring the XJR to my Indie and after too long a period of time received it back with similar issues that I dropped it off with. But, that's another story in itself. I replaced the breather hose from the PCV to the throttle body and that's when I noticed this box and Vacuum line with a metal tip on it just hanging there not attached to anything. I have since learned the box is the Fuel Pressure Sensor at the end of the fuel rail. On top is a 3 wire connector and to the side is an elbow and than this vacuum line with a metal tip which for the life of me have no idea where it goes. I purchased a PDF Manual and scanned through all 6643 pages and still...nada. The manual shows the FPS and the elbow but makes no mention as to where it goes. Can someone please help me? If you know where it goes or can look at yours it would be of great help. Thank you


First time attaching pictures hope they work

 

Really need some help with this one. Anyone have a clue what the fuel pressure sensor vacuum line plugs into? I know its gotta be within the 8"-9" length of hose, but I have spent hours looking and feeling around and left pondering my mechanical abilities at this point and quite frankly waiting for my car to respond with all the talks Im having with it as im sprawled across the engine ...slightly losing it I know. Is it bad after the 5th hour to just start laughing at myself?

 

Hi motofreak72,

I think this hose is in the vicinity you're describing. It fits into a hole in the back end of the intake manifold or supercharger. The first photo shows the general vicinity, and the second shows a closeup. Let me know if I'm looking in the wrong area:











If that's the spot where your hose connects, you can probably refit it with a little J-B Weld epoxy on the outside of the metal tube to help it stay put (thoroughly clean the tube and the inside of the hole with a little acetone or lacquer thinner on a Q-tip but don't get solvent on any painted surfaces).

Cheers,

Don

 

Wow.. under my friggen nose. I love you Don. I hope I haven't damaged the car riding around with it off. Ok, I briefly looked toward the front as everything kept pointing back and the curved hose made it appear as though it was heading under the throttle body(back and down)somewhere , but whatever ill go set it now as you recommended. Thank you for the picture and the step by step.

 

THANKS
