12.2.3 Fuel Pump Drain Lines

This entry is part 29 of 50 in the series 12 - Engine / Propeller

Once I got the drain on the mechanical pump I ran it over to the firewall and had it exit next to the electric fuel pump drain. The next day, I was talking to Malcolm and he mentioned that he likes to combine those two lines to avoid the “forest of drains poking out the bottom of the fuselage.”

That’s all I needed to hear. When Malcolm Collier of Hangar 18 expresses a preference about something related to building a Velocity, it’s pretty much always worth doing.

So I pulled the electric fuel pump drain line.

Spliced in a “tee” and routed the mechanical fuel pump drain line into it.

But now I’ve got a hole in the bottom of the fuselage… That I’ll use for the fuel distributor (spider) drain line.
