Started dry fitting fuel tank plumbing parts, fitting antirotation brackets, running vent line. Also bent float rod to specs and attached to fuel capacity sender. Checked resistance at full and empty positions - close to spec at 30,5 and 249 ohms. Attached vent line rib snap bushings. Played with Rolo-Flair tube flairing tool to understand operation. Pics are from later date, but illustrate fabrication of the vent line.
Parker Rolo-Flair tool - makes precise 37 degree flares
Vent tube after flaring - getting ready to attach fitting
End result with vent line snaking thru ribs to opposite end of tank at high point
