Thank you Al!

You are right… there is no easy access to the large cap on top of the tank. The purpose for that large cap really is to be able to get inside the tank to clean it out. Since I was tight on space on top… I added a bung on the side of the tank that is at the oil fill level. If you look at the first picture you can see the brass plug with the square head on the side of the tank.

To fill the dry sump system for an oil change I remove the brass plug, and use a funnel to fill the tank until the oil runs out the hole. That is the level the tank is designed to run at. When I add 14 quarts of oil into the system (including the oil in the oil filter and lines) for a fresh oil change... the oil just starts to come out the hole. The tank is designed to run at that level. There is a baffle inside the tank right above the bung. The extra volume left over in the tank is to allow for oil level fluctuations as the rpm of the engine changes.

On the bottom of the tank there is another bung with a removable plug for draining the tank. I drilled a hole in the floor of the trunk for access to the drain plug. The oil tank set up in the trunk works good… If I ever need to clean the tank out I can un-bolt the tank and remove it.

Also… the reason I mounted the tank up high in the trunk is so the oil will gravity feed into the oil line that feeds the pressure section on the pump. I wanted to make sure the pump always had a head of oil.
