Default D2 Pressure loss

I had a sudden loss of d2 pressure as truck was warming up earlier. I switched over to veggie and all ran as it should but when I was driving I kept cutting system off to see if any effect and it was intermittent pressure loss. When cut off the pressure would drop for a few seconds then rise back up. I thought it ,ay be the d2 pumpmfailing so I replaced it and filter to no avail. The on.y thing I can think of is the check valves are fouled? However...I added the beefier check valves when I installed AZ Daveís relocation kit a couple years ago so Iíd hope thatís not it. Any ideas?

Those beefier check valves are to keep wvo out of diesel tank. Your issue may be the purge valve or v3 manifold check valve. Dfinitely something you want to keep an eye out on because 3 years ago my manifold check valve went bad and during morning warm ups in winter time i was filling the wvo tank with diesel.
