640 Gas Line Routing?

Can someone post a picture of how the gas line is
routed on a 640? I am replacing the inline fuel
filter with a sediment bowl and new gas line, but
I can;t see how to get it there without either a
crazy long path, or running right on top of the
exhaust manifold.

thanks

ot sure where along length of line that you are asking, but on side of engine it passes between block/head & the manifolds
 
The factory fuel line ran as JMOR says and is behind the manifold and it also has a part of it that was rubber line but made just for the 600/600/801/601 series tractor. I have replaced more then one and used brake line and ran it so it went forward of the manifold so as to keep it cooler
 
Couple of Pictures - Hope you can see the tube.

The fuel line goes forward out of the shut off valve for about 6-8 inches, then makes a 180 degree bend and back the 6-8 inches. Then it takes a 90 degree bend and goes down behind the muffler and through the manifold to attach to the back side of the sediment bowl.

You need take the tank off and attach the tube to the shut off valve. I goes on a slight angle. Then lower the tank down and thread through the manifold and attach to the sediment bulb. A second set of hands really helps.

BTW, the rubber tube old mentioned - I think that was on later 601 series tractors. I think all the 600 series used steel tube all the way. I know my 55 - 660 is all steel

Hope this makes some sense - kinda hard to put into words and harder yet to get a good picture of.
