Hello and happy new year to everyone.

I have a 1989 Sea Swirl 5.0 OMC Cobra [302 ford] and want to replace the old fuel/water separator. It calls for a Sierra 18-7846. I want to go to the 10 micron version it has the 21 micron on it now.

Sierra site says the 10 micron are rated at 90gph. That should be no problem right??

Thank you very much MB

No problem I've been using the Sierra 10 micron ones for years. Think about it, you engine at most wide open throttle would use only about 20 gallons per hr......
