| Step 01: | |||||||||
| Step 02: Make two vent bulkhead fittings and tap bouth sides with 1/8" NPT tap . |
 |
||||||||
| Step 03: Make two wing
tank vent flanges. 09/07/15 |
 |
||||||||
| Step 04: Mill flat on
two sides. 09/07/15 |
 |
||||||||
| Step 05: Layout then
drill a hole in the bottom wing skin. Temporally install a 1/8" NPT fitting in the hole in the skin to center the bulkhead fitting. Square the fitting to the rib and match drill to the skin, cleco as you go. 09/19/15 |
 |
||||||||
| Step 06: Remove the
fitting, scuff, clean and prime. The countersink holes were necessary for the length of rivets used. Builder Note: This bulkhead should have a thinner flange about .090 not .125. 09/20/15 |
 |
||||||||
| Step 07: Install Vent
Line. 09/20/15 |
 |
||||||||
| Step 08: Vent from
left wing tank. Builder Note: I added a mount for a second AHRS in the wing in case I wanted to add one later 11/08/15 |
 |
||||||||
| Step 09: Vent from right wing tank. |
 |
||||||||
| Step 10: Left wing
tank is vented to the outer end of the left wing. See Step:08 |
 |
||||||||
| Step 11: The right wing
is vented the same way as the left tank. The black fuel hose is the vent from the header tank. I used a hose so I could transfer fuel to the to the right tank through the header tank, this will assure the header tank is full. 01/06/17 |
 |
||||||||
| The header tank is
a little over 2 gallons. Step 12: From left to right 1: Fuel out to front fuel pump 2: Not used at this time 3: Fuel in from right tank 4: Fuel in from left tank 5: Vent to right tank The fuel sender is at the back of the tank, this will help to alarm as soon as the float moves from full. 06/26/16 |
