Fuel systems part 1:

The first thing we have to do is install the plastic guides to hold the fuel system pipes. These are easily separated and form using a band saw and 3M wheel. The. You install them with pop rivets. You use a washer on the back of the rivet to hold the shop head. You will need to use a wedge piece to get the top rivet as the holes are too close to the flange for even a skinny cherry rivet puller. Not a big deal.

After that it's onto the fuel selector. Not a lot of work here, just a few nut plates to install, some holes to counter sink and then some screws to install using Loctite 948 to keep them from coming loose.

Once that is done you crimp on two terminals for the fuel pump electrical leads and tie the ground into the bolt using a washer (optional) o protect the lead from Tempe bolt head.

Now comes the fun part. Quite a bit of cutting and bending and flaring (all things I needed to borrow tools for). You begin shy straightening the tube on a flat surface. I found it much easier to cut it into length first and then straighten it more accurately.

It took some time to completely understand the bends but if you use the plane to guide you it's actually pretty intuitive.

This was one of the most fun exercises I have done so far in the build.
