Fuel lines need to be run from the bottom of each fiberglass wing tank, to the header tank behind the passenger seat. Often a shutoff for each tank will be added above the header.
Fuel line routing
Often a grommet is used through the side quarter window lexan or aluminum frame.
Allow enough slack in the line to permit wing folding.
Although these filters are very visible and are the correct type, two in this location is not recommended. Better to locate one after the header and let the header do its job as a gascolator.
Be sure line from pilot side descends toward header .
Line may be routed under rear deck cover.
