Tractor RPM low but when trying to use front loader engine stalls. Ran tractor with side covers off to view fuel filter. Fuel filter starved. Level below filter portion and had the appearance of a waterfall with bubbles streaming inside. Took off the fuel line from the tank at the filter assembly and no flow from tank. Blew some air up in the line to the tank and it started dribbling out. Took an articulating inspection scope and shoved it down the fuel filler pipe, tons of rust inside the fuel filler right elbow. Got scope down in tank and showed tons of globs of rusty looking stuff all over the tank. Followed the other posts info on taking out the fuel sender to get right into the tank. Pull off the red shroud between the instrument cluster and the tractor body. 4 bolts on the outside of the shroud and one in the center of the engine compartment. Take off the Positive battery lead to avoid issues when removing the instrument cluster. Remove 2 bolts on top holding the instrument cluster , then 2 screws below steering column holding the instrument cluster. Start to lift up the instrument cluster from the top and carefully disconnect all 2 piece electrical connectors going to the cluster including the ignition switch. Remove the RPM drive shaft connector at the instrument cluster. Carefully snap apart the gray plastic instrument cluster and lift off being careful free it up from the steering column. ( You can probably remove the fuel sender without removing the instrument cluster but a lot easier to work on the sender with the cluster out of the way) The fuel sender has 5 small bolts, washers, and lock washers holding it to the tank. Remove the two piece electrical connector on the fuel sender wire. Remove the 5 nuts, lock washers, and washers from the sender bolts. Carefully pull the sender assembly out of the tank being careful of the float. My sender unit was rusting to pieces (part of the problem). Now with a clear view of the bottom of the tank, tons of rust metal particles! Put in a strong magnetic pickup tool and swept the tank removing a couple of table spoons of metal rust particles. Then used a mechanical pickup tool with paper shop towels soaked in carb cleaner to thoroughly clean the tank. The fuel outlet is a 1/8 inch hole raised about 3/16 inch off the tank floor. The tank is plastic which was helpful. There is no filter or anything in the tank. Tank now dry. Cleaned rust out of fuel filler tube with emery cloth and recleaned fuel tank with magnet. Everything clean! Problem solved! Tractor runs great. Use this same procedure to access the tank no mater what your clogging issue is.
