Fuel smell 1999 225ox Yamaha

[dfabian]

I am getting fuel smell in hull of my 26 regulator I have pressurized both tanks at 3psi per test spec. It holds the pressure I have sprayed soap solution on all the pickup and vent hose connections and no leaks have appeared. My question, is there a check valve in line anywhere on high pressure side @ the motors that could be faulty causing fuel to feed back to the tanks some how???

nope.
nothing on the engines will back feed or otherwise make fuel in the hull.
its in the hull.

Rodbolt thanks for the response that rules that out.

could be someone spiled gas when changing a water seperator.
