Today's update.  My upper brake hose came yesterday so I installed about an hour ago.  Prepared everything to bleed the brakes however when I go to pumping the brake handle nothing happens when I realized it was not go to work until I find out why I went and removed the furthest hose bolt and  bleeder valve small amount of fluid ran out. both were clear and caliper passed compressed air.   When I pumped now didn't seem to make any difference so I tend to think its the seals in the brake lever?  Allergies wiped me out for the day, so dinner is in the oven and I'll hit it again later or tomorrow.  Installed the two fuel valves and ran some line.  I think I'm going to invest in one of those quick disconnects that also act as a shut off so when I have to remove the tank I will be able too most easily.  If anyone wants to lay into the brake issue, please be my guest.  I'm think that like the o rings in the carb that must of shrank over the years then leaked like a sieve, there may be some rubber in the pump that is not doing its job.   Asta

I'm back, so I took your advice and pulled a vac. on it with some mixed results.  What worked better was to crack the banjo bolt an let some fluid run downhill.  So doing I went back to bleeding the system.  I pumped and I pumped and I started to see the MC level go down, that's about the time I noticed fluid down on the rack deck. Oh #$%* now what.  So I back track and find the upper banjo on the right side was leaking, I tightened a bit and tried again, still leaking, closer look it seemed to be coming from the crimp on the hose.  Drained the system again I remove it put on new washers and switched end to end so it would be at the caliper, easier to see. Refilled and that one stopped so now I'm starting to get fluid into the system, the lever even started to get harder, then I see more leaking on the other side.  Couldn't find my .38 or I would have shot it! It was coming from the hydraulic front brake light switch.  Keep in mind this whole front end is off a GL1000 with duels. Tightened it a little could barely get to it but took one of the horns off and managed to get a bit of movement.  Tried it again still leaked! So I drained the system once more and removed it no obvious reason for the leak so now I'm about to go online and see If I can fined a new on and order some more sealing washers. And the beat goes on.
