Full StarFull StarFull StarFull StarFull StarSierra 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.

Iboats had the best online price for this filter. They also have shipping rates that are lower than most other online retailers of boating accessories. Great company to deal with.

by Emmett from Pearland, Texas on April 26, 2013
This is labeled as a replacement for the Mercury 35-802893Q, but when received the specs reflect it is a 21 Micron filter! NOT the 10 Micron filer I need. I had looked for the specs on-line before ordering and they were not listed. The 10 Micron P/N is 18-7945 according to the West Marine website.

Full StarFull StarFull StarFull StarFull StarSierra Filters Work Great
by Michael from Prattville, Alabama on June 13, 2011
I switched to the 10 micron fuel/water separator filter in 2008 and have had great service from them. I change them every 50 hours and keep spares on the boat. I've never had a clog and I don't have issues with the 10% ethanol fuel I'm running. Great price too!

Q:
I have a merc cruiser 5.7 LX EFI Gen. Current separator is Merc 35-802893T. Which Sierra Separator can I use? See 18- 7945 and 7944 and 7845 and 7844, but all say replace a 35-802893Q and I have series T.?
A:
Unfortunately, the manufacturer only carries for the Q series.
Q:
How can I determine if I need to replace my fuel/water separating filter for a 4.2L 1989 MerCruiser with 1/4" outlet?
A:
It needs to be changed every 50 hours or once a year.
Q:
Does this fit on a GM 302 Inboard engine. 2001 Glastron Volvo Penta ???
A:
Please call or chat in with engine info to confirm, we need manufacturer name, horse power, model/serial number.
