TracTuff D15/D16 Fill Pot


It's not a swirl tank, it may look like one but its not, this is the little brother to the swirl fill, the fill pot! 

Water does not spin and the inlet/ out configuration does not do the same thing to separate air as the swirl pot, but the fill pot is more effective at trapping air then a simple filler neck. The fill pot is a bit easier to make and as a result, less expensive, so if you need a point to fill the cooling system and you want a little more flexibility with where the outlet points, as well as up and down... this is for you! 

You have the choice to move the outlet, change the connection type as well as the radiator cap bung to suit your specific needs. All billet parts are CNC machined from US milled 6061 aluminum. The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. The tank is welded so that it sits level when bolted to an engine with a 7° lean forward (exhaust side).
