I replaced the broken hose this weekend and wanted to post up a few pics to help others in the future.
NOTE: I would seriously recommend all owners inspect the "feed from fuel pump" hose shown in the diagram in my previous post and in my pictures below as soon as possible. It is easy to check and could spare you losing half a tank of gas like I did and the potential for a serious fire. Looks like it may have a much higher probability than the other hoses down near the filter of wearing out due to the high pressure feeding through it from the fuel pump. Sorry for the large font but honestly I think this particular fuel line is a high wear item that I have not seen anyone advise to check specifically. All of the other hoses protruding from the fuel filter were fine, but the high pressure fuel line I have highlighted was much softer than all the other hoses and had hair line cracks all up and down it. I am surprised it did not blow much sooner.
Here is a pic to give you an idea of where the filter and pump are located. Note I have removed the "weak" line feeding from the fuel pump to the fuel filter.
A closer up pic of the side of the filter and pump from which I pulled the cracked hose:
Here is a pic of just one of the many substantial cracks in the fuel line hose I replaced:
I had intended to change the fuel filter but the lines pictured in the diagram as # 5 and # 10 were essentially fused to the old filter (which by the way seems to be working fine). since I was pressed for time in lieu of replacing the part (which had a Merc Part # on it and was not the MAHLE part I had purchased) which I believe to do I would have had to cut the old lines, I decided to let sleeping dogs lie and leave it be.
All in all this is a relatively straight forward job, just a little messy (prepare to get gas on you).
Hope this helps someone else!
