TracTuff PRB/ PRC "Race" 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 catching passing air than a filler neck, this is for you! 

The race fill pot starts with a beautifully machined 6061-T6 flange that incorporates the exact footprint of the OEM neck and machined o-ring groove for the OEM gasket. 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. The race version differs from the standard version in that the flange does not have a water bypass provision. If you would like this style of flange due to intake manifold related issues... I can add a water bypass port to the bottom of the fill pot on request.

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at If you have questions related to the configuration or options... PLEASE visit the WHATS WHAT or FAQ page. The cap bung has a 1/16" NPT port for connection to an overflow and uses early model Honda radiator caps; such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN lines, I 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 hardware kit includes two stainless M6 socket head bolts and a Genuine Honda gasket. The tank is welded so that it sits level when bolted to an engine leaned back 15° (OEM position) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option. 

DISCLAIMER: Depending on your fuel line routing, manifold type, throttle body size, and position... you may be required to make changes. Due to the numerous intake manifold and throttle body combos, I cannot tell you what does and does not fit, if you are in doubt... it is your job to communicate specific measurements to insure that I make the product to your specific needs. Small changes generally don't increase cost but large changes and/ or R&D may lead to additional charges.
