JACK Underwood - Nobodys answered Your question yet. New plastic gas tank, I put one on a K321 (14 hp) I installed in a CC 72. If I remember right the fuel valve on the bottom of the tank is setup to take 1/4" rubber fuel hose. What I'd do is replace the metal fuel line completely with rubber, all You'll need are two small worm gear hose clamps, a foot of 1/4" rubber fuel line, and a hardware store fitting that goes from 1/8 Inch NPT male threads to install into the fuel inlet of the carb and the other end is 1/4" Hose Barb, fairly common fitting a good hardware store should have for a Dollar or two. I know what You paid for the tank, I got one a couple years ago, I know what they cost.... You don't need the sediment bulb either, I'd install an in-line fuel filter anywhere in the hose, another $2. Rubber fuel line isn't "Stock" or "OEM" to a 124, but then neither is the plastic fuel tank. Hope Your's fits under the hood better than Mine did. I had to buy another gas cap that was lower profile, sand off the top maybe 3/8" of the filler neck, and still rework the mounting brackets to be able to close the hood on My 72 with that new tank. I had only a 5 quart tank on the tractor before with a K241 (10 hp) and I had to gas up every 2 to 2-1/2 hours mowing. With the 14 HP it would have been every 1-1/2 to 2 hours. With the 8 quart tank I can run 2-1/2 to 3 hours now.
