Default check valve

the check valve keeps diesel from flowing into the wvo tank when running on diesel. there will be diesel in the v3 manifold while running on diesel. if the check valve is bad then you will get diesel flowing into wvo tank thru the wvo feed line or large fuel line to the wvo tank. if the check valve is bad then diesel flows into wvo tank thru the small line or return. if the check valve is bad, while running on diesel the wvo tank will fill with diesel and the diesel tank will empty quickly. if the wvo tank is full then you will have a mess in your bed.
