Set pump pressure the easy way with this 3/8" x 4AN elbow/filter/GAUGE outlet combo. It works with either the usual 1/4" (6.35mm) Nylon hose or 4AN. -your choice. The liquid-filled gauge reads up to 300psi and the cleanable mesh filter is 85-micron.
If you really are hardcore and need full protection, then our FAILSAFE Outlet System with pressure gauge and sensor is the elite upgrade.
Remember, this is the critical pressurized side. Leaks are avoided via use of quality 4AN and compression fittings. With flammable methanol-heavy concentrations (e.g. 70/30), this is to be taken very seriously.
