Master Cylinder Grommet installation help Options

[tornik550]

My master cylinder grommets have a slight leak. They are cracked and old. I purchased some new grommets. I removed the old ones already and did not pay attention to how they were installed. Which side of the grommet goes into the master cylinder- the wide side or the narrow side? Also, when I install the lines from the reservoir, do I push them all the way through the grommet so the line is pushing against the washer in the master cylinder or does the line rest in the bore of the grommet?

Looks like an easy job but it's not. Patience during and beer after.

My method, lay under the car with drops of fluid running down your arm, push real hard for a half hr or so, stop a few times, throw tools around, kick car, try again, push real hard until fingers are too tired, get more frustrated and give a courtesy half pressure attempt before giving up, they'll slide right in. All i could figure is that putting too much pressure causes rubber to expand, blocking clean insertion, moderate pressure seemed to allow lines to slide right in without over compressing rubber. Good luck!
