Smart racing front oil tank
I have posted previously inquiring on the prudence of and the steps required to install the front oil tank. I am now in the process of doing that. I am using a 72 oil filter console with a thermostat because that is what I have and a Smart Racing tank. It appears that I will need to run 2 ''fill'' oil lines to the tank. 1 from the oil filter console due the thermostat as the oil temporarly bypasses the coolers, and then when the thermostat opens, the other feed line from that console, through the coolers and then into the tank. The way I see it, I just have to add another inlet to duplicate the existing one. I am inordenatly proficient at making unnecessary work for my self, so would appreciate being saved from that by someone(s) who have been here. Thanks, Bob

You are running an oil cooler at the front, right? Put a thermostat on the lines going to the cooler. Like this:

You want three oil hoses going from the front of the car to the back:
1. Oil feed hose 2. Oil return hose 3. Crankcase breather hose All three should be AN-16 lines. Some people like the feed line to be AN-20 but that seems to be overkill. The return hose coming out of the engine should go to some kind of remote console with a filter on it. From there, it should go straight to the front of the car. It should go to the thermostat in the photo I posted in my previous post. From the thermostat, the hose go to the cooler in (bottom). The cooler out should go back to the thermostat and then from the thermostat to the return port on the tank. The feed line should go from the bottom of the oil tank straight to the engine oil inlet port. The breather hose should go to the breather return port on the oil tank. The oil tank should have a separate breather.

Thanks responders all. Is it necessary that the engine and tank be linked with a vent hose. Could the engine and tank have their own individual vent receptacles. That would eliminate the long run from engine to front tank. Thanks again. Bob

 The Vent Hose from the Tank up along the Roll Cage and down to the Motor is necessary. Len

It was explained to me, At high RPMs and load, a considerable amount of oil exchange, not just vapors, happens via the vent lines between the engine and the oil tank, most if not all from the engine to the tank. Obviously it has to be returned which can't happen if the vent tank is isolated. Mo betta understood now thanks.
