i dont know man water is corrosive and the oil might work i dont know i thick that ---- is but the same ---- is fuel came from oil so i dont see why not. people use fuel lines for ghetto oil lines for turbos so just try it
wont work, the gerotor is mild steel. It'll rust, and the oil is too thick, it will overheat. Harbor freight has a sidewalk sale october 2-4th, man up and og buy a real water pump.
i don't think you need a 100 psi fuel pump for a water/oil pump in a a/w inter cooler set up. water might damage the pump (corrosion) and oil would be to thick and might not even pump it. you should look into a bilge pump from a boat supply house. i hear they are cheep and work well for what you need to do. use the fuel pump to pump fuel in your setup. and use water/coolant in the system not oil.
yeah i forgot about blige pumps that wouls be exactly what you need people use them for cheap oil return setups where the turbo is to low to use gravity to drian
