Typically, the larger the engine, the larger your fuel water separator should be. As a general rule of thumb, the required flow rate of your fuel water separator is about 10 percent of the rating of your engine. So for example, a 200-hp engine would require a 20-gallons-per-hour (GPH) filter.

Which is better 2 micron or 30-micron?

Racor recommends that a 2-micron filter only be used in final or secondary filters where the fuel is first filtered by a primary filter. Further, the company says a 30-micron filter should be used as a primary to filter raw or poor-quality fuel before it is further filtered by finer media, such as a 10- or 2-micron.

How do I know if there is water in my fuel water separator?

If there’s water in it it will be clear at the bottom and fuel coloured on top, a noticeable difference. I change my filter every 100 hours or beginning of season whichever come first. If you can’t see the bowl, drain some fuel from the bottom and let it sit.
