The Relaxn 3/8" BSP Fuel Tap N/P Brass drops into a standard fuel line with a 3/8" BSP male thread on one side and a matching female port on the other. You get a clear on or off point in the line, handy near a tank outlet or filter where pressure can reach up to 150 PSI. Turn the handle and you control the flow before you start work on hoses or fittings.

The body runs chrome plated brass, so it stands up well around fuel hardware on boats that cop spray and damp lockers. The 150 PSI rating matches typical low-pressure fuel circuits rather than high-pressure injection rails, so it suits marine tank plumbing and feed lines. The simple 3/8" BSP layout means fewer adaptors and less chance of weeping joints. It is smart buy gear for tidying and controlling small fuel setups.

Q: Can this fuel tap be used in non-marine fuel setups?

Yes, as long as the system uses 3/8" BSP threads and operates at or below 150 PSI. Many small engines and stationary fuel setups use the same thread pattern. Check that your hose tails or fittings are 3/8" BSP male or female to match. Also confirm that your fuel type is compatible with brass components.

Q: Is this tap suitable for high-pressure fuel injection lines?

No, this tap is rated to a maximum of 150 PSI, which is far below typical high-pressure injection systems. High-pressure rails often run into the thousands of PSI. This valve suits low-pressure feed, transfer, or tank shutoff duties instead. Using it beyond its rated pressure can damage the gear and the system.

Q: Do I need thread sealant on the BSP connections?

Use thread sealant only if your existing setup requires it for BSP tapered fittings. Many BSP fuel connections rely on thread sealant or tape to achieve a leak-free joint. Choose a sealant rated for fuel contact if you use one. Always avoid excess sealant that could migrate into the fuel stream.

Q: Can this tap be mounted directly at the tank outlet?

Yes, if your tank outlet uses a matching 3/8" BSP thread and the installation space allows for the tap body and handle movement. Mounting at the tank outlet gives a clear isolation point before any downstream hoses or filters. Just ensure the handle has room to rotate fully. Also support nearby lines so vibration does not load the tap body.

This tap suits fuel systems that use 3/8" BSP threaded fittings on both male and female sides. It fits into marine fuel hose or tank setups where a shut-off point is required in-line. Installation follows standard BSP thread practice using suitable fuel-safe thread sealant or tape if required by the system design. No additional brackets or adapters are specified in the supplied data.
