Not unexpectedly I had a leak at several fittings. I had only hand tightened things so I snugged them up until I had no leaks.
      I also had a leak at the fuel cap. The test procedure has you cover the fuel cap with tape. I found that my first effort was not good enough.  A second effort, where I burnished the tape and seams, and used a second layer proved effective.  I did find that my hand pump leaked a bit so I just clamped the hose shut and all the leaks disappeared.
