4-way shut-offs have a bypass/return circuit to direct fuel back to the tank when closed AND an additional port in the other side that is open ALL THE TIME. This makes it super easy to add an additional pressure outlet to an accessory (high-speed bypass, pump sizer loop, hi-lo valve, etc.).

Provided with fittings including a bulkhead fitting for interfacing with a pump or other ORB type mounting. Please select valve size and bulkhead fitting size below.

If you'd like different size fittings in any of the ports, just say so in the notes section of your order and we'll swap 'em out.
