Continued making the fuel pump tubing today, but first I had to make the threaded spacers for the fuel valve, in order to line up the tubes.
\nHere they are cut to length:

After drilling and tapping threads, I installed the fuel valve to the valve plate.

Then I installed the fuel valve covers

Now I was able to determine the length of the feed line…

Length marked to the center of the fuel valve outlet:
\n\"Fuselage<\/a><\/p>\n

To calculate where to start the bend, I made a bend on another piece of tube, and measure the distance from the bend starting point to the finished bend centreline:
\n\"Fuselage<\/a><\/p>\n

Like this:
\n\"Fuselage<\/a><\/p>\n

Then I marked the offset on the feed line tube.
\n\"Fuselage<\/a><\/p>\n

Vola!

To make the pump return tube (top one in the photo), I fitted the fuel valve and pump brackets in the aircraft:

Final photo with the covers installed.

Next is the tubes that go from the valve to fuel tanks. These are tricky ones…<\/p>\n
