sandhopper,
I managed to find the tank that I have. It was built for Mark Vaught's first car and became redundant when I built his current ride. It measures 22.5" long (including the mount and outlet) and is 7.5" wide. It has a swirl pot to reduce aeration of the returned oil and also has a built in heater element. It holds about 3 gallons in the main body. PM me your cell number and I will send you a couple of photos.
