Racor fuel filters??

[regidog]

Just went and purchased the Racor 3213 fuel filter water separator for my mercruiser 470. Is there a difference for outboard and i/o packages. West Marine had no idea. I cant figure out why there would be. I got the same as http://www.wellcraftv20.com/cgi-bin/yabb/YaBB.cgi?board=Modifications;action=display;num=11 68569511;start=0#0

I'm gonna answer my own question here. Outboards have a clear bottom like the 3213 and i/o have metal bottom. Im not sure why but maybe its got something to do with mixed gas. Not sure, but I know I got the wrong one. West Marine really wastes alot of my time!!! They never answer my questions correctly >:( >:( >:(

There shouldn't be any appreciable difference in the i/o & o/b except in the mixed fuel. The newer VRO or like (pour oil into a reservior) outboards pose no real problem of improper filters causing straining of the oil as the older models of fuel mixed may present. Presently I still run mixed fuel and take care to look for waterlogging from oil.

In case I didn't make my self clear, the older style filters had the capability to inhibit the oil flow and restrict it. This is what happened on the first motor on the boat I now own. Therefore they came out with I/O or O/B water seperators (oil or no oil), the micron size of the filter was probably the only difference.

the only difference between each filter is the base of the filter, teh clear plastic base does not meet coast gaurd specs for installation in an enclosed compartment on an I/O or inboard engine( or even when there is a generator aboard an outboard boat), the aluminum bottom will meet coast gaurd spec for burn resistance( just LIKE A1 fuel line verses B1), the actual filter element is designed to filter gas or premix. the racor elements do a superior job of filtering out debris and water(thanks to the aqua blocker coating on the filer element), and lead to restriction in the filter( they sell a vacuum gauge to check this). Yamaha just released a new spec on all their outboards to use a minimum spec filter of 10 micron, they list the vacuum measured resistance at no more than 4 inHG, mercury uses 2 inHG as a max.

as far as a filter causing an engine problem, as with any filert if you let it clog up it will, but odds are the anti siphon valve was the culprit

Metal bowl for I/o's because motor and gas filter can be installed in the same enclosed area. Outboard is outside the hull and plastic can be used. The motor can be a source of combustion, that's why metal bowl for I/O installations. I researched this a while back.
