Round two for the 280Z.   I filled up the back of my wife's station wagon and drove over to Jai's house.   I put in the battery hold down bracket I fabricated (and my wonderful wife painted). No more twine holding the battery in place. Those are M6 wing nuts holding the two parts of the bracket together. I figure that if a wrench is needed to get it apart, make it a 10mm.   Then I put fuel pressure gauge in downstream of the fuel filter. (Thanks Cliff!) There was no pressure in the line
