fuel line from flow sender to union

fuel line routing: 2015-11-03 Panasonic DMC-FT1

Looking aft from the wheel tunnel, this shows the solid aluminium fuel lines under the saddle of the fuel tank. The one running in from the bottom left comes from the fuel selector valve and goes to the gascolator. The one on the right comes forward from the fuel flow sender and connects to a union mounted on a bracket bonded to the fuselage floor just aft of the wheel opening.

fuel line routing under baggage shelf: 2015-11-03 Panasonic DMC-FT1

Looking down into the access hole on the port side of the baggage shelf. The inlet of the gascolator, near the top of the picture, is fed by a fuel line from the fuel selector valve. A short length of pipe connects the gascolator to the fuel pump at upper left. The pump connects to the fuel flow sender (at lower left) by an unseen length of pipe. That pipe includes a straight section of about 150mm, like that visible along the lower part of the picture - this is to reduce errors in the flow sensing caused by turbulence. This picture was taken before the baggage bay bulkhead was bonded in place, and before an access hole was made in the fuselage floor for the gascolator bowl. The fuel flow sender bracket is not yet fastened to the inner rib, as there are reinforcing layups to do in that area after bonding in the baggage bay bulkhead.

fuel line bent to shape: 2015-11-06 Panasonic DMC-FT1

This is the shape of the fuel line between the fuel flow sender (at left) and the union at the edge of the wheel well. Note the straight section at left to reduce turbulence in the flow coming out of the fuel flow sender.
