Well, I put a new piston pump in. Turck started out at 15lbs of pressure for the first day. 10lbs at WOT.
...lol, well I left the truck out in the sun and nowI only run 10lbs at idle and 5 at WOT. At least It's not dropping down to 0 anymore. I'd sure like to know why it does that. Wonder if it is something in the gauge??
I've got The dual fueler sump is still in the box. I'll get it in when I can.
