NOTE THE CENTER HOLE AND THE OFFSET SIDE HOLE ARE 3/8 NPT’s. (national pipe tap) AND THE 2 HOLES THAT HOLD THE FUEL TAP IN THE CENTER ARE 12 X 24 JUST LIKE THE ORIGINAL ALSO THIS IS THE SMALLEST OF THE 3 DIFFERENT TANKS THAT FORD MADE AND THE ONLY ONE SIZE THAT I KNOW THAT IS BEING BUILT AT THIS TIME. Nice quality replacement at a fair price. It will fit right in place of the original tank without any problems because all Fords from 1953 to 64 have the same mounting hole spacing. It is made of STEEL and is painted silver. It has 2 (two) outlets on the bottom one for the 1953-54 models and one in the center for the 55 and up models comes with a plug to plug the hole not needed for your use. If REPLACING A 10 INCH DEEP TANK on a /801/901/400 4 cylinder 3 different tanks could have been used, flat front or tapered front, 8 inch or 10 inch deep or diesel. YOU will need to put your OWN fittings on for diesel NLA. No longer available you could have the tapered front 10 inch deep NLA. Or 8 INCH DEEP FLAT FRONT WITCH THIS IS the only tank available new that will work. BUT IT WILL NEED a 1 1/2 TO 2 INCH SPACER UNDER THE TANK we use square tubing others use 1 1/2 wood or a std. 2 x 2 from the store. Some people lengthened the legs on the tank brackets. This is to keep the flange on the gas tank from hitting the flange on the underside of the hood. No adjustments to the tank are needed but the brackets may needed to be modified….. WE DO NOT JUST SELL PARTS ON LINE I REALLY DO WORK ON TRACTORS IN MY SHOP AND HAVE MY OWN MACHINES TO DO MOST ENGINE MACHINING AND METAL.
