Hi!
First and foremost, PLEASE be very very careful. Stay well away from the leakage area with the engine running. High pressure fuel as I'm sure you know can inject right through the skin, eye, etc - really bad news!
Buy some white aerosol spray foot powder, dry everything off well with compressed air, then spray everything down with the white powder. Start the engine just briefly, and shut it off, then look for the damp area which the powder will easily show. I'm guessing we may have to replace either a connector tube or the rail itself.
Thank's for the idea I will try that this week any idea tho what can be leaking in that area? I replaced the two lines and the rail is dry and all the line's coming out of rail are dry

I was thinking the cross over tube nut is loose. But that will open up a new can of snakes. It has to be fixedOriginally Posted by AccurateDiesel

Is that a hard or expensive fix if it is the crossover tube?
No. new tube is $36.75 - not really any more difficult than changing the line.
Thank you I will do your trick and check it do I need new seal's or a new tube? and If i understand I must torque the tube's correct? and you guy's are great!
Thanks! Yes, current recommendation on connector tube torque is 41 ft-lbs.

Pulled the tube out looked new had a orange o ring which looked in good shape I put a little grease on it and reinstalled and torqued it down...also can I run the engine with the lift brackit off to make it easier to look for leaks?
