Today I noticed that the hardline coming off the water separator is leaking at the bottom fitting. I tried to tighten it a little more, but it didnt stop the leak totally and I didnt want to tighten more and risk cracking teh line or completely busting the fitting. I thought I saw a site that link on here that you can order Mercruiser parts. Anyone know where I can get these kind of lines?

try this one http://mercruiserparts.com/

YUP,,
BAM is the way to go

Heres a dumb question... I looked up the 600SC for the line that goes from the fuel pump to the filter/separator and the pic shows the shape of an L, but the one I have is almost like an S shape.. Are those drawings accurate, or are they just more of a reference to the part? Just want to make sure I order what I need..

The drawings are for reference only and are not accurate. If you have any doubts, then call Marc at BAM and he will be glad to help.

Thanks... I ordered the line. I have it on a 2 day ship so I can hopefully fix it this weekend..
