222 Tank '05

[Muffinman]

hello friends,

I need to inspect and flush the tank on my 222. I m having fuel flow issues when cruising in choppy seas, I also find small solid residues in the pre filters. I was wondering what I should expect to find inside the tank....are there deflectors or bulkheads (longitudinal or transverse)? I plan to insert a hose with pressurized water in the hope of getting past any bulkheads. advice is welcome Thank you

When you get into it check the anti-siphon also if equiped. Had to change one out on my old boat cured the fuel starvation. If I loosended the filter, just crack it, it would release the anti-siphon and it would run again for a while. Get me home.

Drag the boat around, stir things up, get the bow up high, pull the sending unit. Using a piece of copper tubing and an automotive fuel pump and a primer bulb you can completely drain the tank. I like to put some dry ice in the tank to eliminate explosion hazard. You can get an inspection camera in there to see how clean it is.

The debris could be from fuel fill hose or fuel line breaking down. Could also be corrosion inside the tank.

Hello guys,

here we are with this old tank ready to take a walk outside. But I think it will take a few beers before we can see it out.
the first problem now is to slide it out, since the rear bulkhead does not allow it to be moved behind.

do you have any suggestions? should I cut that bulkhead?

Thank you

If you take those 8 HDPE blocks out you may be able to slide the tank and lift it out. Make sure you use a new Philips head bit that is properly sized, slow speed drill (careful with impact tool - not recommended), get in proper position, get behind the screws with perfect alignment and take them out. If you screw this up you will make extra work for yourself trying to get them out. When re-installing use a Torx head screw instead.



The tank doesn't look that good. Problems are usually on the bottom. I would consider replacing it. I see your in Sardinia - not sure what resources you have available there. Also consider replacing all the hoses and anti-siphon valve. With the tank out cleaning should be easy. The baffles should not be a problem.

Also here is a link to my Islander tank replacement. May be of help to you.

Decided that this is the year to replace my 25 yo fuel tanks. No leaks. I plan to keep the boat. I'll document the process here.

Pulled the hatch. This hatch was rebuilt a few years ago with Coosa board. Looks good and feels solid. Hatch was set with 3M 4000 - kept everything sealed. Some difficulty cutting with blade to get it up. Not sure what it will go down with. Deck ports were caulked in from the underside as well. Kept the tanks dry.



I also put plastic over the fill, sending unit and pickup. This deflects any water away from the busy area of the tank.

Luckily I was able to remove the blocks without any problems, but the two remain at the front, under the console, which there is no way to access. The tank is housed about 10 inches below the console, which limits maneuvering room. I'll keep you updated.

With the rear and side blocks out is there enough room to slide the tank to the rear out from under the front blocks and raise the rear of the tank up to remove?

 

[Hookup1]

Hard to tell which end is the front of the boat. I'm guessing the fuel fill hose is to the front?

Is the tank "loose"? Can it be pulled away from those blocks?

What is the length of the tank? And length of the opening? Will the tank come out if that bulkhead is removed? Is there a removable hatch behind that bulkhead?

Can you cut the deck above the tank and get it out?

Yes, hard to tell front from back... can we assume the fuel sender is the aft end? Can you use the fuel sender hole as a handgrip and lift up? The pictures make it look like there is enough room between the tank and the aft bulkhead to do that.
