Moline 706 Clogged Injector Lines

Here�s the problem. I am working on a MM 706 Diesel that has been sitting in the AZ heat for many years. The fuel in the injector lines has evidently cooked off and formed a very structural plug in the lines. I have tried air pressure, carb cleaner and inserted wires into the lines to clean them out. I am down to the last plugged line to unplug and none of the above has worked. My only remaining thought is to apply heat to it and see if the fuel deposits loosen up.

Does anyone have any other options for removing this hardened old fuel buildup?

Thanks!

The heat worked! The clog came out after warming up the injector line with a small torch and applying air pressure. The clogged injector lines was a first for me. It seems the intense heat down here causes some unique problems when tractors sit for 20 or 30 years.

I will probably have the same problem with my 602 that has bee sitting for 10-12 years.

I think I would try one more thing before "heat" as from a propane torch if that is what you have in mind. I think I would have it boiled in very hot water first and then find away to hook up a fitting to force steam though it just after it came out of the water. I am afraid the heat from a torch make make the line britle and it may just crack or break too easy.
