SIERRA
Replacement 10 Micron Filter Elements

High-performance fuel injected engines require ultimate fuel filtration, separation of water from the fuel supply and maximum fuel flow. Sierra's new filter elements deliver all three of these critical performance factors. 7900-Series 10 micron filters eliminate harmful contaminants at over 90% efficiency, while removing over 99% of emulsified water. They''re engineered for today''s sterndrives and inboards, along with 2-cycle and 4-cycle outboards.

Today's ethanol-blended fuels increase the chances of water in fuel tanks, resulting in premature wear, poor performance and component damage. Contaminants of over 10 micron size also can cause severe damage with the close tolerances of today''s fuel pumps and injectors. That is why a high efficiency water separating filter is so important. Sierra 10 micron filters were independently tested to JIS, SAE J1839/J905 and ISO 4548-12 standards.

Switched to these filters because the Racors were substantially more expensive and I was going to change this water/fuel separator filter regularly anyway. The Racor I was using had a clear bowl beneath the filter with a drain. That was nice. Since the switch, I've gone Non-Ethanol with Sentry and have had no water issues since. I might add that I also switched from two 20 gallon vented deck mounted gas tanks to three new EPA West Marine red portable six gallon gas tanks that are only vented when the engine draws gas. I mention this because of 4 carb rebuilds over the years thanks to issues from Ethanol...

I am replacing these replacements on a boat I bought in the spring. They have a lot of rust on them, but the boat is performing well, so they must be working well enough. But I am replacing them with the Yamaha original equipment for $1 more per filter.

Comments about Replacement 10 Micron Filter Elements:

I've been a customer of West Marine since the 70s in Miami, the 80s and 90s in Minneapolis and since 2002 in Punta Gorda, FL. One thing has always held true - if I needed something and I went to West Marine, they would have it. Not necessarily the lowest price (this item happened to be on sale so it was a "best buy"), but THEY HAD IT when I needed it.

                      Inexpensive replacement for OEM which is hard to find, and for the existing EMP 35-06031 filter- in line with a carburated '93 Johnson 150 Ocean Runner using premix.
