RC 4.8m Water in fuel problems

Evening all,

As above really. I have done about 20 odd hours since owning my Ribcraft and love it to bits but just have had trouble with the water in the fuel symbol flashing on. Twice its happened now. According to the manual the water sensor and filter needs emptying so have done that and solves the problem however it keeps coming back on after about 6 hours use. I have a S/S fuel tank so i know about the condensation but does this have its own water separating filter if so is that causing my problems?? Hope this is enough info sorry its a bit basic. Also been looking for additives to put in the tank such as QS 'Dri -fuel' do these really work and help.

Many thanks in advance.
Si

I know it's hard these days, keep your tanks full ... this helps to prevent condensation...

regards

My outboard is too old to have a water sensor (luxury) but I have added a cheap water separator between the tank and outboard (CAV Diesel Fuel Filter / Glass Water Trap marine boat | eBay) and I find water in the fuel a couple of times a season - more so when filling up from fuel barges than local garages.

When you empty the filter, is there actually water in there? If so is it salty?

No there doesnt seem to be water in there. I cant understand how water even gets to the engine filter when the filter from the tank should 'catch' it first? Could it be a tempermental sensor?

Pikey Dave, just ran all the fuel out the bottom of the filter under the console nothing untoward not even a drop of water. So i emptied it into a jar to make sure. Nothing! Guess the sensor is dodgy?

Usually the sensor is a ring of foam or similar that sinks in gas but floats in water. There is a detector in the housing that triggers when the ring floats up off the bottom.

Could be that the sensor is triggering without anything happening; could also be that the ring is sticking in a positive condition (i.e. not returning to the bottom of the sump.)

Note that if you're getting an alarm, it has to be triggered by a filter with an active detector; third party water separating filters *usually* don't get wired in, and will not trigger any alarm. A quick glance at the filter housing should ID a standalone - there won't be any wires coming off of it.

Thanks for your response. The one under the cowling is the sensored one thinking of changing this for a new unit and see what happens but at the moment cant get any fuel through which is bloody frustrating probably doing something simple, wrong!
