Your full solution that filters fluid, mounts a pressure sensor (failsafe), a pressure gauge (for tuning pump output), and also accepts standard 1/4" (6.35mm) tubing OR 4AN line is here!
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.
