I am running a 1 tank system and just added a raycor 500fg and am not getting enough power it wont pull itsself up hills. Have went thought 3 filters tonight so I am not sure if I have all the water out but I think so.I have 2 inline filters and the rayor I think I need to add a second pump any ideas and what to use would be most helpful.

Are you heating the oil before it's injected?

An electric pump in addition to the stock lift pump is needed because of the high viscosity compared to the correct fuel.

I have a inline glow plug type system a vow2.
