Oh okay, no problem! Yes that is the evap line and they collapse due to age and exposure to fuel vapors. I actually just replaced the one on my expedition, just carefully split the line with a razor blade at the green fitting and remove the fitting. Replace the line with fuel hose then retest to make sure that it doesn't collapse. If there is still an issue with the line collapsing, the canister could be restricted or the a restriction between the tank and the purge valve, but the canister is the prime suspect.
