Location of fuel/water separators

CAVU · Posted: Wed Nov 10, 2004 8:00 pm Post subject: Location of fuel/water separators

I have two small fuel/water separators, one for each engine, located under the splashwell. This makes them difficult to check/change etc. I am considering relocating them to the splashwell. Does anyone use this location and have you had any problems with this?

Cavu- When I had my new Yamaha 90 EFI engine mounted, the service tech mounted the separator/filter inside the engine well forward and above the boot that contains all the wiring and the gas line for the engine. The location is great, as the gas line from the tanks comes forward out of the boot, into the separator/filter unit, then back to the engine. It's up high enough and far enough forward to be easily accessible from the cockpit underway, or from the outside of the transom on the trailer. Any spillage or leakage goes out the drains at the back of the well through the transom, not onto the cockpit floor. The unit has two inlets and two outlets, one of each on each end. The pair to the rear are used for simplicity in connecting/routing. The gas inlet line comes from the port/starboard selector valve, so only pair of the inlets/outlets are used. Couldn't imagine it being mounted in a better location. Joe.

The splash well is the place to mount mount one for the reasons Sea Wolf mentions. Cleaning and changing filters is best left to when the boat is on the trailer.

Ken, the fuel filter/separator on 3rd Byte is also located under the splashwell. Pretty awkward to get to for an 'ole guy like me. Both my previous C-Dorys had the filters mounted in the splashwell and that is, in my mind, the only way to go. Readily accessable and easy to service. Seems like a function over form thing to me. Sea Wolf has it exactly right.

Mine will be in the splashwell before it hits the water this spring.

We are the same as Sea Wolf, works great.

Thanks for all the replies. I have my fuel tanks out of the boat now, dealing with another repair and it seems like the right time to relocate the fuel/water separators to the splashwell.

Hi fellas, Mine is in the splashwell and the outlet is teed with one hose going to the Accumix R(for kicker) and the other to the main http://www.c-brats.com/albums/album61/IMG_1848_001.sized.jpg . Pete

Mine didn't work very well under water -- and that well is full to the brim when backtrolling and trying to hold position over a hallibut rig. But we all boat like we all boat.

Mine is located under the splash well between the tanks, on the transom. This will be a good location for me as I am installing a fuel flow meter and the sending unit needs to be downstream from the filter. I intend to mount the sending unit above the starboard tank against the starboard vertical wall of the splash well on the inside. The existing fuel lines will be easy to connect to the fuel flow sender as they are right there.

In the process of relocating filter to splashwell near boot. Mine was in batt compatment and suffering effects of acid and very hard to change or check. My question - I want to put a quick connect on the inlet side of the filter head in the event I ever have use of an auxilliary fuel tank (just plug and play). Would my fuel system be compliant with various regulations concerning integrity of fuel systems? Any comments on this arrangement? Thanks - Dave

Back to the top for this old thread!

My Racor filters are inside the sponsons mounted to the transom. I don't like having them inside for several reasons. Access and safety are chief among these.

Where are yours mounted on the TC255? All my fuel/electrical lines come out of the transom in a boot and conduit arrangement to the engine. Steering is in another conduit.

I'd like to mount the filters on the transom, to be accessed from the Armstrong bracket but hesitate to penetrate the transom again and will still have the problem of getting the fuel output from the filter back into the conduit to the enginel

Ideas? Pictures?

Thanks..

Charlie

Hi Charlie,
What a nightmare to have them mounted inside the transom!

Mine are mounted on the outside of the transom. I don't have any pics handy but they are basically right in front of the engines on the transom.

You don't need a new hole, your fuel lines are already running through the transom to the engines. You just need to re-route the lines through the existing holes to allow sufficient slack to run the fuel lines through the filters.

First thing to do is remove the filters from the inside, fill the screw holes with the 4200/5200/LifeCaulk, then mount the housing on the outside. Then you just need to add fuel line as necessary for the new routing. Be awfully careful while making the bridge connections with your fuel lines inside the transom assuming you want to do that. Make sure they are not leaking and really secure! Let the whole transom compartment air out good with the doors open after you do the work if any fuel happens to spill out. There should be NO BATTERIES connected to your vessel during this operation in case the bilge pump were to kick on or such. You may just want to avoid the perils of a bad bridge connection and route a single piece of fuel line from the pickup on the tanks right out through the transom to the "fuel in" port on the filters. We are technically supposed to change the fuel lines every two years per Suzuki but I think that is a bit aggressive.

Famous last words...but it should not be too hard of a project. I would personally be most concerned about measuring and making the holes to mount the filter housing on the outside of the transom nice an even.

Good luck!

Depending on your engine,this is like a dream come true [maybe]......This handy rigging accessory Makes the entry into a rigging tube from the external splashwell mount fuel water sep. into the engine easy !
Quick down side in salty places[like here]fuel water filter heads [the part your fuel lines connect to]need to be stainless as they rust fast in the splashwell.
