Spent yesterday configuring my oil system on the RV-8.  I should have heeded Rusty's warning on those "Easy push-on oil line fittings"  The Summit description says "no more busted knuckles trying to assemble oil lines".  Ha!  I'm an FAA "standard 170 lb pilot" but that is not enough force to put on those blasted fittings.  Anyone know a trick to make them easier to put on? 
 
Hi Tracy,
 
You did see the instructions that say to put oil on the fitting, right?  You could probably do a small AN-6 line without it, but you'd never do the larger ones.  It really seems wrong to put oil on these, since they're just a friction fit, but they ain't coming off. 
 
(for others) My joke was that there's a 180 lb minimum weight limit for the AN-12 size fittings.  In other words, if you can't put at least 180 lbs (and twist), they won't seat.  I had the fittings in a vice, on the corner of a workbench.  One foot was on the workbench, and the other was on a ladder next to the work bench.  The trick was suspending all of my weight on the hose, while twisting.  This requires a lot of faith in your vice, and sense of balance, particularly when you realize what part of your anatomy is suspended precariously above the vice during this operation :-0   
 
BTW, there is a press type tool for doing these hoses, and I presume it's expensive, unless you can "borrow" (perhaps not the most accurate term <g>)  one from work :-) 
 
Tracy (finally getting my XM weather activated)
