Fuel line testing goes on

After 24 hrs the pressure went down some, so I had to search out another leak.  Luckily this was easy to find as it was at the end cap I put on the return line in order to test the fuel line. I tightened it a bit and the pressure is holding at 15 psi. (In fact it held here for one week as it was a week until I could get back on the project)

Time: .25 hrs.

Pressure holding steady at 15 psi.
