Off topic but...
So I am thinking of looping the return back into the wvo fuel feed before the filter to keep the heat up near the engine instead of returning to the tank and bringing up less warm veg on a two tank wvo system.
I will have a 3 way valve on the return line to be able to loop or send back to wvo tank to purge air on filter changes etc. My objective is to increase the veg fuel temp.
My main question is if the return from the engine has air in it that could cause issues?
Thoughts?
Thank you.
