Could anyone tell me if the fuel lines from my tanks have any check valves installed? I can't see them or get at them without tearing apart the aft cabin floor. Point being, I want to disconnect the fuel intake lines from the selectors and blow compressed air down into the tanks to agitate the gasoline, this to mix in the E-Zorb for E-10 Fuel. This is according to E-Zorbs directions.
I cannot get an air line down thru the Fills, around corner elbows, etc. I have diluted the required amount of E-Zorb with 2 gallons of gasoline and put this mixture into each tank, It's almost like a glue consistancy, I have diluted it somewhat.
Has anyone ever had any experience with this, or any other ideas how to aggitate the fuel? Boat is out of the water and tanks are full and have been treated with Racor fuel stabilizer, I had forgotten to put in the E-Zorb.
Any replies are appreciated. (1988 340 Sundancer Twin 7.4's)
Thanks, Captain Don
 
I did it.

I E-Mailed Searay Customer Service through their Web Site requesting the informatioon I had posted. 1 day later I could not believe it, I got a return phone call from a person who identified himself as a Plant Supervisor, he told me he has been employed at the plant for 32 years and he knew exactly what I was trying to do.

I followed his directions, added the E-Zorb, bubbled the fuel in both tanks. Now I'm happy.

Yes the reply from SeaRay was amazing! He directed me to remove the fuel tank pick up lines from where they connect to the fuel filters. Then connect an air source, the line is unobstructed right into the tank, I was concerned that something, like maybe a filter,check valve, or something was on the end of the pick up tube, but he said there was nothing on the end but an open tube right to the bottom of the tank.
I took my air compressor it has an adjustable regulator. He told me to use between 3 and 5 lbs to bubble the gas, he said this is how they test the systems for leaks when the boats are new. (A safe procedure when done properly)
I had a 50' air hose, I ran the compressor about 100' upwind, away from the boat, bilt up the pressure. Unplugged it dragged it over to the boat. With my hand on the regulator I gradually increased the pressure to 3 lbs, I could hear it bubble, the gas fumes were coming out of the overflow tube, downwind, and dissapated.
I disconnected and refilled the compressor three times, to do each tank, I bubbled each tank for roughly 10 to 15 minutes. It was a simple procedure, very easy to do.
I apologize for the long explanation. If anyone wants to do this, I rather be safe and not leave anything out. :thumbsup: Capt. Don
