I prosealed the grommets on for the vent line, and stuffed some kleenex in the vent tube and slid it down the tank. I did this to ensure that no proseal would find it's way into the line. I remove the klennex and bingo. Vent line in.
After a good wipe down with MEK, I then slathered proseal on the rib #1 and the mating surface and cleco'd it together.
I was very careful not to get any sealant on the other vent line. Once all was clear I hand tightened the vent line in.
Then I went to town squeezing rivets. Once done, I cleaned up with MEK. Last item was to torque the vent line fitting at the rib.
