I only fill my RIB out of the pump at the service station and I believe they are fairly well filtered (never had any problems with crappy fuel in the Humber anyway) but I wonder whether the fuel tank breather is likely to let water in when you are out in rough conditions - it seems to get everywhere else.

A separator with a glass bowl is a good thing and something on my "to do list" (which probably means it won't ever get done but....)
You will find that the sensor on the E-tec is very sensitive to any water in the fuel, it pings up as soon as there's a hint of water, i use a main water seperator between the tanks and the engine as well as the one on the engine itself.

I unscrew my water/fuel filter regularly throughout the season and pour the contents into a jamjar. There's usually a half an eggcups worth of water in there. The petrol is saved for the strimmer and the shite gets chucked.

A RIB fuel tank and contents will be at a different temperature to external "ambient" quite a bit of the day, the change in temperature is the causal factor.

That's how Roy put mine together, there is a Volvo water separator under the seat and the separate filter on the engine. Going on what Mollers said above I will have a better look - it isn't a clear bowl but I think there is a drain bung in the bottom of the filter body so assume I can loosen it and pump the shite (if any) out with the priming pump. I've probably used about 400L of fuel so far so I guess an eggcupful or two of crap would not be unreasonable.

I've been through 1,000 litres or more over the last year and there hasn't been the tiniest drop of muck or water in my bowl. I replace the filter each year, so by default the bowl gets drained.

That has the be the key, keep your bowl clean and keep a beady eye on it.

I've been lucky with my diesel cruiser too - not a drop in the bowl. However, the diesel from the fuel truck goes through 2 (of my own) filters before getting into the boat tank. Prevention is definately better than cure!

So why do people hide them in the console or under the seat

Embrace your jamjar. Cherish and be proud of your jamjar, for it is a thing of beauty.

On a trip to Hawaii a couple of years ago, I was treated to a private dive trip on the divemasters' personal boat (17 foot Whaler, as I recall.) We ran about 10 or 12 miles south of Kona, did a couple of dives there, and were due to return. No start. A bit of troubleshooting on my part led to a fuel starvation cause, at which point I asked when the Racor filter had been changed. Answer: Never. The bowl had become somewhat opaque, so it was impossible to see what was inside, and the canister itself was corroded onto the mounting bracket. Luckily, the two other divers are big guys, and with a decent application of muscle were able to get the bowl off the cartridge. It was packed solid with a reddish-brown (read: rust) fine silt; looked like a lump of jeweler's rouge for a buffing wheel (but smelled like gas, so you probably wouldn't want to use it for that.)

After trying to come up with a safe way of bypassing the filter, we ended up scooping/scraping/wiping the crap out of the bowl, and were able to get enough fuel going through to make the run back up to the harbor.

The water separator/filter works, but it does need to be checked/replaced every so often.
