Cowl work, Drain valve, fuel site tube

We spent several hours making small incremental cuts on the top and bottom cowl, along with judicious sanding, in order to get the top and bottom pieces to fit together properly.  At first we didn't think they could ever fit, but the fit wasn't bad once modified.

Some brass elbow adapters and tubing were installed on the header tank for a fuel site tube.  Versilon SE200 clear tubing (from McMaster Carr) was used for the site tube as it has an inner liner that is resistant to ethanol.

A drain line was also installed from the header tank to a fuel valve under the fuselage (for fuel testing or draining). Due to the shape of the fabric underneath, we were unable to use some of the parts from our kit, but we purchased a 1" brass bulkhead fitting (1/4 NPT) which worked well.  Also, an inline fuel filter was installed.  A filter here was recommended by several builders as it will catch any debris that could cause the fuel valve to start leaking.  Hours: 14
