Fuel Filter
A bit of advice would be appreciated.
I use two 5m Zodiacs as part of a SCUBA club but we seem to have continuous problems caused by water in fuel. We currently have sealed metal fuel filters mounted on the transoms of the boats however as these are sealed it is not possible to see what is going on, if water is accumulating etc. I have been thinking about changing these for clear plastic filters (also transon mounted) with valves on the bottom to drain any water/crud. Has anyone had any experience of using these type of filters in this environment and have anything to recomend or steer clear of? Also is the plastic stong enough to withstand rough treatment of both divers and their equipment!? If not it might be necessary to construct some sort of cage around the filter. All advice gratefully recieved Anthony |

You need what's called a water separator ... includes a filter, but
water collects in the bowl. Remove (unscrew) the bowl now and then to remove the water. Head down to any marine supply shop, they'll set you up. |

The link the Chuck sent you is a good place to get a top of the line fuel
filter/water separator set up. Since you have already thought about the concerns of the plastic bowl set-up, no more needs to be said except that metal blows are available from Racor as you can see. However, there some other alternatives. It sounds like you already have filter separators, the transom mounted spin-ons are usually 10 micron filters/ water separators that function the same as the spin-on Racor replacement elements. ( am referring to the Racor elements that will screw on to your existing heads). The main difference in their functionality is the Racor's ability to be drained via a pet cock. With your existing spin-ons you can just spin them off and dump them in a bucket. If you do this, be sure to put the elements back on ASAP as the rubber gaskets starts to swell quickly once removed making their refitting a problem. But what I would be most concerned about is what is causing the water problem in the first place? Maybe you have an above deck poly tank? if so, then pay some attention the vent. If it can be closed, then close it while not underway. If the tank is constantly being splashed with water then something to deflect the splash, maybe have some vinyl tank covers made or maybe some simple plywood covers like an inverted box that could also be used as a seat?. I think with some "looking into" you will find a better solution than just being able to more conveniently drain a bowl. Anyway, I don't think better(more expensive) filters are necessarily the answer to the problem. -- Ron White Boat building web address is www.concentric.net/~knotreel |

If your filter/water separator has a drain plug on it, it should an almost daily routine to draw a sample to see how much water is in the bowl. The only think is that I do not think I would like petrol fumes sloshing about in the bottom of the boat, but I assume its open without sparks & flames, so it is not as bad as in an enclosed boat. -- Tony Brooks www.TB-Training.co.uk |

They park the boat for weeks with the tanks empty just so it can breathe in all those wet night airs and rot the bottom out of the tank. You're talking about something that takes real work on their parts, landing twice with the fuel dockage, when they're all tired out from sailing all day with a boat now filled with grumpy, drunk passengers who want to go ASHORE...and who will abandon the captain to dock himself at his slip because the fuel dock is SO close to the parking lot!...(c; No wonder they don't stop to fill up and prevent condensation...... |

Well...it seems that just because one draws off the water/contaminates from
the bottom of the fuel filter bowl, doesn't mean that one should just let it drain into the bilge. Draining it into a cup/bottle (i.e. that won't 'melt' from the diesel fuel). Also, Diesel is significantly different from Petrol/Gasoline...one can pretty much put out a cigarette in diesel while this is not very adviseable with gasoline. Glenn.

The modern plastics on fuel filters are made for commecial mishandeling
I have used them in engine rooms and lorrys. if you can see water you can drain it. test the fittings and polycarbonate bowles by smacking them with air bottles etc on dry land if it breakes you have lost the fitting but the alternatives are still available alloy etc. good luck ajw wrote: A bit of advice would be appreciated.
