Default pump failure

Okay. So my pump went bad. I installed a new pump and system seemed to be working until I noticed that my main diesel tank was overflowing. Seems that the system was pumping Veggie into my main tank. Upon re-checking things my system light will not come on in Auto position. I am not sure what to check now. I have removed and cleaned sensors on the manifold and all appear in working order??? If I leave system in Auto mode after driving around and then turn off it purges like usual.
Any help or ideas would be greatly appreciated. I am stumped
Scott

If you're pumping WVO into your D2 tank I would suspect the check valves on the D2 lines. If your check valves stay open there's nothing to keep the WVO from entering your stock fuel system.

Yep and this leads to the lower pressure so it wont work in auto correctly.
could also be return purge valve.

Default thanks guys

Thanks for the help guys. It appears that after 6 hours of cleaning and checking just about everything that there was some sort of blockage in the veg oil fuel line coming out of my tank?? There was little or no flow to the pump. I removed the hose and blew it out with air compressor but never saw what it was. All is working now!

Thanks again. Whew! I hate paying for fuel now, I am spoiled.

Did you address this? You certainly dont want WVO in the diesel tank.

Default whoops

Thought I had it fixed but spoke to soon. Must be the check valve has gotten stuck again as main tank is overflowing and being filled with wvo.

Might want to look into AZ Dave's check valve set-up that goes on the fuel bowl.

Or if you want to go hog wild, his whole plumbing kit:
