  1.  I plugged the return line on the reg and bumped the pump with the gauge teed in. It started at 50 lbs and I left it overnight, about 17 hours and it dropped to 35. I can't see that little bit of leakage flooding the motor. I have spent a long time looking for troubleshooting diagrams and the ones I have found really don't tell you anything.

  2.  I ran new lines and they all match the diagram. I made a tee with my gauge and it is 50 lbs with just the pump on and just under 40 when cranking. The pressure bleeds right off when just the pump was on but it holds around 40 when cranking and holds it until I cycle the key back on then bleeds right off. Wouldn't start and when I pulled a plug the cylinder had a lot of fuel in it. I verified we had spark afterward also. 

  3.  I am trying to get an understanding of the fuel plumbing, somebody may have replaced the lines at some time. The line coming out of the filter from the pump tees off and goes to the rear injectors. There is a crossover to the front injectors and the front ones are plumbed to each side of the regulator and the line on the top of the regulator goes back to the return on the firewall. Does this sound correct? I have tried to find diagrams and am not having any luck.
