i have a 1999, 751 skid steer. the fuel tank has bushing or plug at the bottom to drain the tank. The chain case also has a bushing or plug to drain. Each is protected by a plate over the bottom to keep the plug from being knocked out by a stick or something on rough ground. My plate fell off which i did not notice and a stick dislodged the bushing or plug. i managed to get it back to the house before i lost all the fuel. I order a new plug but they sent the wrong size. i was in pinch so i went to the local hardware store and bought a rubber plug with bolt throught the center when tighten would seal. My question: will this cause a problem in the long run. the tank is plastic and i am concerned at over time the pressure will slit the hole. i tighten the plug pretty tight. any thought or ideas if this is okay for the long haul? Thanks stephen
