Installed the 2 new oil breather caps and routed hoses to tank. ....there was only enough hose for one side that came with the unit, so I had some red 3/8th air hose laying around I used for the second cap (until I can find more of the blue hose.)  mounted the tank on the rear of the motor on the elec. term bracket. Ran the exit hose from the tank to the carb/intake vacuum port. Total install time maybe 15 min.

Then we went to the lake.

 It kept the oil normally misting from the old breathers off the valve covers, so it works as intended.     The only change I will make is they just have a screw off type fitting on the bottom of the tank to drain it. I'm going to Tractor supply today to get a small drain "flip valve" to make draining the crap out of the tank a cleaner operation.

Looks good! Thanks for sharing. I found a black one on eBay that will match up with my block and heads perfectly like your blue.

    good deal..... it was a breeze to install. And the best part is...it WORKED.

I had a guy weld a peice of stainless across my ski tow, think it turned out nice..

I would assume long hair people never sit in the backseat? 

I am getting ready to install this on my boat. Can you drill the vents on the back of the valve covers towards the rear of the motor or does one need to be up front? My valve covers are un drilled.

If it were me and it is a jet boat, but them on the front. Have fun.
