Hello folks more knowledgeable than I:
First I do have a manual for my 730 diesel and have searched it and found nothing so far! With that said I have a fuel leak on my tractor and just looking for info before I tear into it so I know a little more of what I am getting into before I tackle it. There is a fuel like coming off the top of the #2 filter housing that comes back along the right side of the tractor and goes into the side of the engine block just over half way up the block thee is a 90 degree elbow this line connects to and the 90 degree fitting screws into the block, it leaking right where that elbow goes into the block. When I take this connection off will fuel flow out of it from gravity feed from the fuel tank? my real question is do I have to shut the fuel off? Second is there supposed to be some type of dope on that elbows threads where it goes into the block? Do you know if this is a flared fitting where the fuel line goes into the elbow? Its been leaking for a long time based on what I had to clean off the block and I got it clean and drove the tractor today to confirm where the leak was and it needs to be fixed. Any words of wisdom would as always be appreciated!
