| Quote: | | When the oil injection system called VRO came out, fuel lines leaking air really became a problem, and caused over oiling. That is when OMC started using the 'Snapper' plastic clamps. If correctly sized, and tightened, the 'Snapper' clamp makes a full circle of pressure and reduces the chance or air leaking into the lines. |
I remember when I had to bleed my VRO2 System (on the water) and broke the ratchet-clamp, or "Snapper Clamp". I then used a zip-tie because that's all I had.
Next time I saw my OMC (Johnson) Tech he spotted it immediately and gave me the whole nine yards on why the zip was a bad idea.
He insisted that the ratchet-clamp was superior because it gave a uniformly consistent seal where the zip COULD allow air to pass through.
Just as Larry explained above, this would result in an over-oiling condition.
I was a bit skeptical because the zip LOOKED like it was sealing tight, BUT, I relented in the face of my tech's conviction about it.
Ever since I've kept a supply of the OMC Clamps on hand for any fuel/oil related connections.
VRO still running strong at 22 years.

Larry-
Thanks! "You da' Man!"
I've seen those hoses on drag boats!
They have had the Nitro Nationals on the Sacramento River at Red Bluff for many years up until now, when the environmentalists objected to backing up the river to form a lake, etc.
Fun to see 6,000-7,000 or more hp light up a 20 foot boat for 1/4 a mile!
Have a great Memorial Day Weekend!
Joe.

I've been a network engineer for 20 years and have used thousands of cable ties (also called wire ties, nylon ties, whatever...).
Thing to remember when pulling them super tight is that you may have to remove one of them someday.
It is frustrating trying to cut such a tie when they are pulled super tight and you DON'T want to replace every wire it holds.
I always told my guys to leave enough room for wire-cutters.
Just a thought... |
