Outside tinkering today still chasing why my Benz won't shutdown. Since I have tested and ruled out everything except ignition switch valve and vacuum pump I started with the pump. Hooked up my hand pump to use the gauge because it's the only one I have, sure enough vacuum bouncing between 5-10PSI. So I start to look at the pump and realize the hard line bracket to Fuel filter mount is broken. Upon removal the hard pipe has rubbed a hole in the side. Any ideas where I can find one of these? I pretty confident I could repair, however I would prefer to just replace unless cost is unbearable.
