Chris....
Here's some of how I did mine...Tim may have already set you up though...
I take it you have the 4' SS line?? if so, there's not alot of room to play...you'll have very little to spare..
I opened the hole up that was right next to the vac tee....i ran thru it and 90'd up to the gage...I just cut the corner of the cowl for the line...If you remove the wiper cover it'll be easier to maybe feed the line in...
I also ran power/grd with the line...I tapped into my parking light and used the Green ground bolt by the battery...very tit to wire...
