I bought a 1983 Kubota L2002 from what I've found it is pretty much the same as the L275. I kept having fuel leak from the bell housing around the starter. I looked at my service manual and found that there was a drain plug on the bottom of the bell housing. I removed the plug and drained about 2 cups of fuel from the bell housing. I thought, ok someone spilled fuel at some point and it drained into the bell housing. I restarted the tractor thinking that things were all good. After about a minute fuel began to drip out of the bell housing again. I have checked everywhere externally IE: Tank, hoses, fuel injector pump and have found no leaks.
