I just bought a 1985 18' Outrage and it has a Racor fuel water separator installed on the transom. The unit has the clear bowl on the bottom with a drain nozzle. How does this collecting bowl operate? It appears to be full of gas at the moment. When there is water in the filter will there be a visible line where the water is seperated from the fuel and I can just drain the water out until I get clean fuel from the drain nozzle? When I loosen the nozzle now the liquid appears to be completely gas.

Nedmack,

That is correct. If there is water present it will appear in the bowl because water is heavier than gasoline.This is how fuel/water seperators work. If water appears, use the drain to drain it out.

Also make sure that you make the drain nozzle sufficiently closed and tight after draining to avoid sucking air into the fuel system through the drain.

While I was draining some fuel out of the separator I noticed some air bubbles comming up from the nozzle. Do I need to bleed my fuel line now? The engine is a fuel injected 140 Suzuki.

There will always be air bubbles when you drain the bowl. The air is needed to displace the liqued being drained. The only way I know to prevent the air is to gently pump your priming ball when the drain is slightly open. I have never had any problems with air being in the gas lines with many carburated engines and one Ficht injected engine. I would not recommend the metal bowl reelescape1 changed to because you can not see if your bowl has any water in it without draining some fluid out. I have never had a problem with the plastic bowls other then them getting "foggy" from age.
