Fuel filter water separator question

**cheapNdisgusting** · 03-31-2012, 06:52 PM

I just installed a 16 gal. fuel tank on my pontoon boat. Always before I used 2 6 gallon Attwood portable tanks and there was usually a little crud left in the bottom. I always dumped it out and started clean. With this big tank I won't be able to do that.

The 50hp Merc uses 50/1 fuel mixture and in Missouri the only kind of gasoline I can get is 10% ethanol. I know that ethanol absorbs water, and I always use Sta-bil, and 90 octane gas.

I want to add one of those spin-on fuel filters (looks like an oil filter) and this is where my question comes up. Some of them say "Fuel filter" some say "Fuel water separator". I want to do both so do I need 2 of them or is there one that does both?

I just put a moeller clear site on my boat. It has the spin on filter the cartridge is also threaded on bottom for a clear fuel bowl with drain. About the same as a racor 320. I will say it looks like it belongs on a D9 or something seems like over kill io me.

I use the fuel water seaperator from wal-mart some will say aww thats not good enough but I have had it a long time and it stil works good. I change the filter once a year and more if nesessary.
