TracTuff P13 Fill Pot


The fill pot is the mid-range choice for P13 (P13/ PCB (H22A/ F20B) cylinder head cooling system upgrades! Better than a filler neck but not as good as a swirl pot but still a great solution for systems that have tucked radiators, a radiator without a cap bung or for situations where you want a higher fill point to aid in burping the sometimes troublesome cooling system. 

The fill pot pot starts with a beautifully machined 6061-T6 flange that incorporates an angled exit port for a seamless transition to 1.25" tubing. The backside of the flange has an OEM o-ring grove for a positive seal against the cylinder head. The outlet can be configured for standard hose (1.25" OD), -16, or -20 male flare.

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at 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 swirl pot includes two stainless M8 socket head bolts. The tank is welded so that it sits level when bolted to an engine with a 10.5° lean back (traditional) or 4.2° lean forward (QSD H2B).
