Washers too thin
by Seaby from Soperton, Georgia on September 17, 2013
The washers are too thin, much thinner than OEM. When I installed the unit I was unable to tighten the connectors enough to stop the gas from leaking. I had to reuse the old washers and the leak stopped.

Sierra Fuel/Water Separator
by Andrew from Pensacola, Florida on June 01, 2012
The products arrived prior to estimated delivery date and received in great condition. The only thing I did not find is the smaller washer that goes into the bottom of the bowl, other than that, I am very pleased that I purchased 2 of them. Buying 2 from iBoats.com was less expensive than purchasing one locally.

Maybe bad batch?
by William from Mullica Hill, New Jersey on June 01, 2014
Bought two of these filters for my Mercruisers. Replaced my fuel filters like I do every year. Port engine stalled out after running for 10 minutes. Wound up pulling out filter to check and the bottom part where the paper goes in to the flange with the o-ring had come apart and glue was restricting the fuel flow. Had to go buy one local. 30 minutes later out in the bay the starboard engine died. Same thing. Over $100 down the drain.

Sierra Fuel/Water Separator
by Andrew from Rogers, Ohio on May 01, 2012
With gasoline now contaning 10% ethanol, removing water from the fuel is important. Ethanol attracts moisture from the air, and moisture in the engine is bad news. I've used Sierra fuel/water separators for years, and never had any such related problems with water. They should be changed yearly, more frequently if you run more than the average.
