I had an issue last year. I always fill up on land. I had 3/4 of a tank, my boat was stored in an un-heated garage. I would heat it for a weekend here and there to work in the garage. The temperature swing made my tank sweat. Had a whole bunch of water/phase separation occur. Had to pump all the fuel out and refill with fresh. What a nightmare. Took me all summer of swapping filters, pumps, lines, and carbs to figure out what actually happened. My point is moisture doesn't always come from the fuel itself.

O-ring or seal dry rotted out or cracked or missing to seal the gas cap is another water source that seeps down in your fuel fill into your gas tank from waves, rain, or just plain old washing your boat. Storing your boat in humid conditions can sweat condensation of the top of your fuel tanks.

The source of fuel does not matter and E-0 Non ethanol fuel did not fair any better when water contaminated it than E-10. If you think water in the fuel is only a current issue because of E-10 this is totally not true as marine engines had fuel water separating filters for the past 35 years as water entering the fuel can take place however....

That is correct about the Stainless steel filter mount with 3/8 holes from Sierra 18-7776 as the same one I sell but dealer cost is around 45 bucks it retails for around 72 bucks. The other one is a kit with the black filter mount comes with 2 - 3/8 plug fittings and the 10 micron filter for 50 retail.

BUP you mailbox is full. How do I order from you?

Thanks guys. I suppose Ill set it up like sep ---> pump ---> post filter ---> rail

Sorry hit my email make sure you put a title on it so I know who it's from.

Mercury recently came out with this. I am not sure of the inlet size, it looks like the same old bracket to me. And a stainless bracket sure sounds like a good idea. But the filter element looks pretty good.

On the Diamond Marine website they have a 3/8" fuel filter kit listed under Engine parts-> Fuel system Parts...no pricing!

Mark, I run these. 1/2 ports and wix 33405 separators. 22 bucks per filter base here, same base the marine perf vendors sell for 45 each. The filters here are 12 bucks each, at the marine perf vendors, almost 30 bucks each.

thanks Joe

One last tip guys, You might want to look at Racor water separating filters with an alum. canister that screws on to the bottom of their filters :It has a nut on the bottom so you can drain the water accumulation out and then close it back up without having to remove the filter... It screws right on to the merc brackets and they also offer different fuel flow rates in their filters ......Two complete units cost in the $120 range Jim
