Began installed fuel tank in wing. Formed the aluminum fuel line to fit through existing grommeted holes in ribs. installed flare AN-6 fitting on the ends. Found that position of fuel line at NR#1 doesn't align with the hole in the fuselage. Need to figure out a remedy, or use the supplied rubber fuel line. The fuel level sender sits too high to fit under the wing skin cover. I will need to make another cover with a raised bump to fit over the fuel level sender.
