I ran into a problem, then out of patience.
I replaced the grommet where the two hoses pass through the firewall to the evaporator with a new one, since mine was torn and I could see light through it. That part is very much not fun to replace, it's a real tight fit and took a good 30 minutes before I got it in place. Then I tried to pass the new hose through it to measure for length, and the grommet popped back out. I decided to just measure the hose without the grommet and add an inch or so to make room to recenter the hose, cut the new hose, then realized that in my efforts wrestling the hose around, it had gotten gouged on the sheetmetal of the firewall. I cut the gouged portion out of the hose, but it's too short to use for that location again. Fortunately I bought way more hose than needed, so I'll be able to try again this week.
I did figure out that the best way to pass the hose through the grommet seems to be to heat it up with a hair drier, and add a bit of lubricant to the end of the hose. I'm undecided on using silicone grease (shouldn't hurt the grommet) vs pag oil (wont contaminate the hose). Any thoughts?
