Fuelab 63713 Fuel Cell Vent Kit for QSST 10AN Pushlock 5/8 Hose Filter Clamps

Compatible Systems

• Fuelab QSST (Quick Swap Surge Tank) fuel cell systems - provides the complete venting circuit from the QSST's rollover valve to the vent filter
• Universal - may be adapted for use with other fuel cells using 10AN rollover valve fittings and 5/8 in vent hose connections with some modification

Fitment Notes

• Designed specifically for Fuelab QSST fuel cell systems - some adaptation may be required for other fuel cell brands or configurations
• Connects at the 10AN rollover valve port on the QSST and routes through the 5/8 in fuel vapor hose to the vent filter
• Proper fuel cell venting is required for safe operation - the rollover valve prevents fuel spillage in the event of a vehicle rollover while the vent filter allows the fuel cell to breathe and equalize pressure during filling and operation

Features

• Complete vent circuit in one kit - everything needed to route from the QSST rollover valve to the vent filter is included; no additional fittings, hose, or clamps required for a standard installation
• 10AN pushlock fitting provides a secure, tool-free connection to the rollover valve port on the QSST fuel cell
• 5/8 in fuel vapor hose is specifically rated for fuel vapor service - do not substitute standard hose not rated for vapor or fuel compatibility
• 5/8 in barb connector joins the hose sections and transitions between the pushlock fitting and the vent hose
• Yellow vent filter identifies the vent line and filters incoming air to prevent contamination of the fuel cell while allowing pressure equalization during fuel filling and thermal cycling
• Hose clamps ensure positive retention at all hose connections - no fuel vapor leaks at the barb connections

Product Description

The Fuelab 63713 is the dedicated Fuel Cell Vent Kit for Fuelab's QSST (Quick Swap Surge Tank) fuel cell system. Proper fuel cell venting is a safety and performance requirement - the rollover valve on the QSST prevents fuel from escaping if the vehicle inverts, while the vent filter allows the cell to breathe and equalize pressure during fueling and normal thermal cycling. Without a correctly assembled vent circuit, a fuel cell can build pressure, vent unfiltered air, or lose containment in rollover situations.

The 63713 kit includes every component needed to complete that circuit: a 10AN pushlock fitting that connects directly to the rollover valve port on the QSST, 5/8-inch fuel vapor hose rated for vapor service, a 5/8-inch barb connector, a yellow vent filter for easy identification and air filtration at the terminal end, and hose clamps for secure connection at all barb joints. Everything ships as a matched set so there are no compatibility questions or missing components at installation. Designed for Fuelab QSST applications; may be adapted for other fuel cell systems using 10AN rollover valve fittings with 5/8 in vent hose routing.
