TracTuff PRB/ PRC Billet Water Neck w/ Fill Pot
It's not a swirl tank; it may look like one... but its not. This is the little brother to the swirl tank, the fill pot!
The inlet/ outlet configuration really doesn't do anything to actively separate air like the wrapped and staggered inlet/ outlet found on a swirl tank and as a result, the fill pot is easier to make, resulting in a less expensive product. So if you just want a fill point that does a better job of statically catching passing air than a filler neck, this is for you!
The fill pot starts with a beautifully machined 6061-T6 flange that incorporates the exact footprint of the OEM neck, a machined o-ring groove for the OEM gasket, and a 1/2" NPT water bypass port. You can chose from a list of options to make the product as unique as your project; including outlet position and accessory ports for aftermarket sensors and/ or turbo and wastegate feeds, as well as two different styles of radiator cap bungs.
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 firstname.lastname@example.org. 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 billet neck has a 1/2" NPT water bypass port and the hardware kit includes a hose fitting and a plug in the event you don't plan on connecting a bypass hose. The tank is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option. Depending on your fuel line routing, this may require you to make changes and due to the numerous intake manifold and throttle body combos... it is your job to communicate the measurements I need to avoid after your purchase has been made.
