The Relaxn 1/4" BSP Fuel Tap N/P Brass gives you straightforward on and off control for fuel lines running up to 150 PSI in small engine or tank setups. The 1/4" BSP male to female layout drops into standard marine fuel plumbing, so you can isolate tanks or accessories without reworking the whole line. The compact body fits neatly beside filters, primers or hose tails on tight transoms.

The tap runs a solid brass body with a chrome plated finish to handle constant exposure around tanks and bilges. The 150 PSI rating suits low-pressure fuel hose rather than injection systems, which keeps it in the right lane for small outboards and auxiliary motors. The 1/4" BSP threads match common marine fittings used across a lot of Aussie rigs, so this valve is a smart buy when you just want practical, known-spec gear that works.

Q: Can this fuel tap be used in high-pressure fuel injection systems?

No. This fuel tap is rated to 150 PSI and is suited to low-pressure fuel lines rather than high-pressure injection rails. High-pressure injection systems usually run far above 150 PSI. For those setups you need hardware specifically rated to the higher pressure range. Using this tap beyond its rating can damage the valve or cause leaks.

Q: Is the 1/4" BSP size compatible with standard marine fuel fittings?

Yes. The tap uses 1/4" BSP male and female threads, which are common across many marine fuel fittings and accessories. This lets you pair the valve with matching hose tails, filters or tank fittings already using 1/4" BSP. Always check your existing gear markings or measure thread type before buying.

Q: Can this valve be installed directly into a fuel tank outlet?

It can be installed where the outlet uses a 1/4" BSP thread and the pressure stays within 150 PSI. Many small tanks and fittings use this thread size, so the valve can sit close to the tank for simple isolation. Always use suitable thread sealant that is compatible with fuel. Avoid overtightening to protect the brass threads.

Q: Is the chrome plated brass construction suitable for coastal use?

Yes. Chrome plated brass handles typical marine and coastal exposure better than many plain steel fittings. The plating adds an extra barrier against corrosion while the brass base metal copes well with moisture. Regular inspection and rinsing after saltwater use still helps extend service life. Pair it with other brass or compatible fittings to keep the setup consistent.
