Saddle Tank Cleaning

[tsubaki]

No, water is thicker than gas.
I would also suggest mixing oil in the fuel to make it easier to identify a leak.
I removed mine, rinsed with water and kept emptying and repeated rinsing till I was happy with the cleanliness. Then added about a gallon of gas to help remove leftover water and other possible trash.
The sending units being removed during this whole process is helpful.

Oh and don't be tempted to pressure test one of these tanks.
Before they leave the place of manufacture there are pressure tested at around or less than 15psi.
Look at this thread.

Page 11 starts the with the tanks and page 21 is where one did have a leak.

Thanks for the responses.

First of all the tanks are dry, and have been for years. I just run from portable tanks but I want to check them out and get them useable to gain back space taken by the portable tanks. I like the food coloring idea to determine a leak.

I think I will fill them in the boat just to see if they leak or not. Then I will remove to clean and replace all the lines while they are out.

Think about it...if they are dry, take 'em out before you do anything else...those saddle tanks are EASY to remove and like Spare says, replace all hoses anyway...if there's crud in the bottom, you can put some gas in, shake around, soak, then shake some more and get the crud out..easily done out of the boat...if there's a leak, better spilled on the ground than inside your boat...good luck and let us know how it cleans up...

I emptied mine and used a heated power washer. That heat broke all kinds of varnish gunk out. I took them to have some fittings welded on the end about a inch up since the dip tubes had pin holes in them.
