Default diesel being pushed to wvo tank thru both feed/return

Hello ,
I have a 2001 f-250 that I have not been able to use since Feb. I am not a mechanic, and my mechanic doesn't know what to do, so it has set.
When the truck starts it pushes diesel back through both the veggie feed tube, and the veggie return/ perg tube.
When I saw this first happening, I simply had my mechanic replace the two ck valves that usually need replacing( it has happened previously so I was conditioned to assume this was the fix ) Nope. I was told it was probably the purge tube sticking open and to put a ball valve on the purge tube and if I did this I could just switch 3 miles before stopping. I did this but diesel is still flowing back through the veggie feed tube.
My mechanic then found another larger ck valve in the unit that was gummed up so he cleaned that well and put it back , but no dice again.

Calling the company is not an option I have found, and there are no installers/ representatives in my area of NW Missouri. I have all kinds of veggie, and nothing to put it in.... Very sad situation

Does anyone have any suggestions? I appreciate anything you can do for me.

Default purge valve and check valve

sounds like you need to replace both the check valve and purge valve on veggie stroke system.

Its either the manifold check valve or the purge valve. Easiest way to find out is look at your fuel pressure gauge and clamp the fuel return line. You have to see what the fuel pressure is when that line is clamped and it will help you figure out but most of the time its the manifold check valve.

Thanks for responding. Do this test while running on D2 or WVO? Thanks
