Allsoyixia 2-Piece Remote Mount Vent Valve Kit for Fuel Tanks — Metal 5/16" Barb, Check-Ball Venting

Alsoyixia's 2-piece remote mount vent valve kit keeps fuel tanks ventilated while preventing pressure or vacuum buildup for safer, more reliable operation.

This compact two-piece kit includes remote-mount vent valves designed to be used with a vent line on small fuel tanks and auxiliary containers. Constructed from durable metal and fitted with a 5/16" hose barb, the valves allow air to pass while preventing undue pressure changes. The kit can be separated and mounted where convenient, and installation requires the valve to be mounted vertically so the internal check ball sits correctly in the bottom fitting.

How does this vent valve keep a fuel tank from building pressure?

The valve permits airflow into and out of the tank while preventing liquid or contaminants from entering the vent line. A check-ball mechanism lets air pass but cushions sudden pressure changes, helping the tank equalize without trapping vacuum or excessive pressure.

• Metal body resists deformation under heat and vibration.
• 5/16" hose barb fits common vent tubing for secure attachment.
• Internal check ball reduces sloshing and fluid migration into the vent.

What do I need to know before I install it?

Mount the valve vertical so the check ball rests in the bottom fitting and follow the included guidance or video for routing the vent line. Installation can take time; ensure fittings are tight and the hose reaches without kinks.

• Position valve vertically — check ball must sit at the bottom.
• Use 5/16" inner-diameter vent hose for a snug fit on the barb.
• Secure with a clamp if required to prevent leaks or detachment.

Will this kit fit my existing fuel system and how durable is it?

The 5/16" hose barb aligns with common vent tubing sizes used on many small fuel tanks, ATVs, generators, and marine auxiliary tanks. The metal construction offers longer service life than many plastic alternatives when exposed to heat, vibration, and fuel fumes.

• Universal 5/16" barb suits standard vent hose sizes.
• Sturdy metal parts resist wear in harsh operating environments.
• Kit splits apart for flexible mounting locations and configurations.

How should I maintain and troubleshoot the vent valve?

Periodic inspection and clearing of the vent path will keep the valve functioning. If airflow is restricted or fuel is found in the vent line, remove and inspect the valve for blockages or a stuck check ball, then reinstall vertically.

• Inspect vent line for kinks, debris, or fuel contamination.
• Replace if the check ball sticks or metal components show damage.
• Contact Alsoyixia support and reference the installation video for help.

Who is this for: This Alsoyixia 2-piece remote mount vent valve kit is for mechanics, hobbyists, and boaters who need a reliable, compact vent solution for small fuel tanks, auxiliary jerrycans, generators, or off-road vehicles. It’s particularly suited to users who want a durable metal alternative to plastic vents and who can mount the valve vertically and follow the installation guidance for correct check-ball positioning.
