Can anyone lead me through the fuel line bleeding steps for l260, I drained fuel tank and replaced fuel line at bottom of tank. Ever since this and an oil change 30 weight oil. I have had a hard start, and temps are in the 50's here in ky. Tractor is very hard starting runs good once I get it going, but will not restart easily. Thanks for any help.

Read this article for a fairly thorough process. Not exactly your tractor but will give you all the steps.

From memory on my L185 which is similar to yours, there is a bleeder on the top of the filter and then another on top of the pump.
I think if yours will run then you should just bleed off the air at the injectors. It may just be running on one or two cylinders.
By the way the L260 is not a gray market model.

If it's starting and running, you don't need to bleed it.
If it's hard starting it either has a glow plug, compression, or injector problem.

If there is air in one injector line would it ever bleed out past the injector?
I agree that the OP probably has some problem other than air in the lines but I am not sure that the air in one line would bleed out or just never crack the injector open.
What do you say?

I guess it is possible to have a completely vapor locked injector, but that would be very rare because when you increase rpm you increase fuel flow and bypass flow and it should eventually self bleed the air back to the tank.

Thanks for the feedback. I have never had any injector problems (yet) so don't know too much about their operation with air in lines.
Thanks guys for the help I haven't replied in awhile because im unable to get it started even after the bleed procedure above with line off I have a very small mist of fuel coming from injector pump which maybe the root of my problem.
