I have been looking at aftermarket tanks but haven't found one yet that suites me. Right now I'm using a 2 qt. clear plastic peanut jar with a screw on lid. My heater core is higher than the top of my radiator (stock) and therefore I wanted to keep the cooling system free of air so that it didn't "air-lock" in the heater core. I ran the 1/4" hose from the filler neck nipple to the jar with two holes in the lid, one for the hose, one for atmospheric pressure balance. It's been working correctly for several years. Summit Racing has a vast array of them.
