Did you find any instruction on how to convert over from the rubber hose above the tanks, if so can you share?
I've fought a power loss problem over a very long period of time (years) at high cost to find and it seems to be going back to the fuel line replacements. We have one more test that will happen soon as the engine runs fine with the outboard gas can connected to the carb. Inspection of the VISIBLE system looks good back to the new fuel solenoid.
my final test will be to connect the generator fuel source to the engine fuel pump. IF SUCCESSFUL, I will have to drop the tanks to see if the fuel lines are crushed.
It's been a long darn haul to get here and I have to admit, I've lost a lot of the spirit for the GMC.
I am thinking metal lines would be less able to be crushed and starve fuel to the engine if this is the actual root of the problem.
thanks for any thoughts, as well to everyone else who over the years have offered thoughts of help. I cannot thank you all enough for your help in the past, and possibly in the future, even yet.

Larry,
My fuel lines were actually not that old, but they were cracked so as to only leaks when the tank was over full but enough to let air into the system all the time. Also and just to add to the interest, the fill vent line up in the frame rail literally came down in pieces.
I have lost track of the best pictures. They were good close ups of the how to cut the bulge off and put compression unions on the sending unit and attach metal lines. I think those were Emery's but I sure can't find them now. I do have a picture for you at:
http://www.gmcmhphotos.com/photos/fuel-tank-lines/p61891-fuel-tank-lines.html
This is how I attached all the metal lines to my tanks. The last I had to mess with this was about 8 years and 50k miles back. I did enough then to make me certain I did not over-do any of it as I have not had to do any of it again.
I also have two recommendations of reading for you from a guy (yours truly) that had the misfortuate opportunity to learn a lot about getting GMC tanks down and back up with a minimum of drama. The second is a mod that you should do while you are there. The best thing to do would be to search out and read all of both threads.
