Which Fuel / Water seperator is best?

[Canopy Locked]

Title says it.. Which pre-filter water separator is considered to be the best for use on a petrol fuel system with a big out board.

With the increasing use of Ethanol in fuel and the sophistication of todays (expensive) outboards, this seems to be a vital piece of kit.

I would suggest the one designed for the Mercruiser inboard petrol engines, Sierra do an aftermarket one so probably available from Keypart surprisingly cheaply.

Racor is widely used here in US. Offer a wide variety of types and styles, gas and diesel, inboard, outboard, various flow capacities, variety of micron choices.

IMHO Racor 500 or 900 depending on your engine size. However, there is a Chinese copy available on EBAY that is very well made for about half the price.

I have these on my boat, and buy industrial filters from the same firm for my business. We have carried out extensive performance and quality checks and would definitely recommend these, known as Headman or Rongsun.

There is also a cheaper Baldwin style water sep on EBAY that I have on my portable polishing / filtration unit.
