225 Johnson oil in fuel

[bighh7]

Ive got a 225 Johnson and am getting oil in my racor , the fuel is clean in the tank but it seems to be feeding oil into my fuel line and going back to the racor , any ideas ?

Is this after the mtr has been sitting for some time or what?? Model # would also help.

Theowner runs the boat often , but lets say yessitting for a while . This is only on the stb engine and not the port one .

Check the fill cap on the oil tank to make sure it's venting. If the oil tank builds up pressure when sitting it can cause this prob.

I'm not a JohnyRude guy but on the Mercs there's a check valve in the fuel line before the pump. Might be one on yours too. Check the manual.

JohnyRudes don't have them.
