Pressure in fuel lines

I have a MF1105 that I just bought and am wondering if anybody knows if the fuel line between the fuel pump and the injector is pressurized when the tractor is off. One line has a drip leak at the point where the fuel line attaches to the fuel pump. There is a nut there that i figure needs a new seal but I want to know if that line is pressurized before I remove the nut, and more importantly I am wondering if the fuel line will reprime itself once it has been removed or does it need to be bleed to the injector?

Any help would be greatly appreciated.

MERRY CHRISTMAS FROM KENTUCKY!

It is a 354 Perkins. The drip is coming from where the nut on the long line attaches to the cast piece that actually bolts to the fuel pump. If I loosen that nut and separate the two pieces is there a seal in there that can be replaced or should I just get a new fuel line and bolt it to fuel pump and injector. Also, are you saying that if i fix leak with new seal or replace fuel line and bolt it to pump and injector it will self-prime?

Again, thanks for the help.

If it is leaking it should eliminate any chance of pressure being there, although I would say there should be none. Cracking the nut loose would release any as well. You may have a small crack in the line, rather than a bad seal at the nut. Check the flared end of the line- drag a fingernail around it, if it catches, the line is shot. You'll have to prime before you retighten the line at the injector. Just turn the engine over until you get good flow.
