I built the fuel pickup tube anti-rotation bracket from some 1 x 1 angle
stock. I used a 1/4" bit followed by a Unibit to cut the 9/16" hole for
the tube.
I drilled holed in the access plate for the fuel line AN elbow fitting
and for the two rivet holes. I the applied lots of the PreSeal
substitute that Van's sells on anything that can leak and then riveted
the bracket into place. I tightened the AN fitting nut to squeeze out
the ProSeal.
I drilled the holes for the nut plates for the access cover. I then
dimpled the rib and countersunk the re-enforcement ring on the inside
and screwed everything together. There is one tooling hole that is
covered by the gasket but it is really close to the outside of it. I
haven't figured out how to close it up. I have read about people using a
rivet but it would be under the gasket, perhaps interfering with its
ability to seal if it isn't completely flush.
I then drilled the fuel cap flange into place The flange has a very sble
bend in it that has to be lined up so that it will follow the countor of
the tank skin
While playing around with the drain valve I noticed that I couldn't
screw it into the flange part beyond about a thread or so. I looks like
the valve and flange are threaded differently with the valve having
finer threads.
