Purchased fuel tank, 13100511521. Tank is sourced directly from manufacturer so everything was identical to original tank except that they have increased the size of the fuel outlet hole to match their newer models.
If your making the same repair/replacement be aware that the fuel grommet being sold to match the tank (13211504920) WILL NOT WORK, they are too small for the tank outlet. If you have already bought the wrong grommet use a short piece of 3/8" ID X 5/8" OD fuel line about an inch long, to stick in the hole. Your fuel grommet will fit tight inside of this line with no leaks. Make sure the 1" piece is for fuel and made of the old fashioned nitrile rubber.

As noted by others, grommet does not fit the new tank. It is too small for the hole.
You need to find a larger grommet that does fit, or use a rubber cork with a hole in it.
1. Remove three screws holding tank to engine
2. Remove fuel hose from carburetor
3. Remove fuel cap and save. Discard old tank (with hose and filter inside)
4. Slide clip over hose about 1/4 inch from one end
5. Insert filter into end of hose
6 Slide clip over the hose where filter is inserted
7. Slide grommet over the over end of the hose. Be sure that orientation is correct (small end towards filter. Position grommet approximately 2 inches from end of hose.
8. Insert filter end of hose into the new tank
9. Do NOT insert grommet at this time.
10. Attach tank to engine with the three screws.
11. Attach end of hoe to carburetor
12 Hold grommet against the hole in tank. Make sure that the hose is not stretched or kinked. Adjust the length of the hose until there are 2 smooth curves in it.
13 Insert grommet into the tank. Ensure that is seats completely.
14 Fill tank part way with clean fuel and tilt the engine until the grommet is covered by the fuel. Check for leaks around grommet and carburetor connection.
