12.2.3 Electric Fuel Pump Drain

This entry is part 27 of 50 in the series 12 - Engine / Propeller

The electric fuel pump has a drain that must be routed overboard. The port is tiny. It’s a 1/16″ NPT. Since it’s a drain line with no pressure, there’s no need for high-pressure lines. I looked for a 1/16″ NPT to barb fitting but all I could find was an AN4 fitting. So I ended up with aluminum tubing. At least I won’t have to worry about dry-rot on the line. 🙂
