I didn't do any research yet, but I was guessing the SKREEM would shut down fuel as well. if not that's great news!
I just watched a video to check the RCM and excited to look at that as soon as I get home today. Fuel pump, regulator and filter should arrive tomorrow. Car has been sitting for a few months, and rail is dry no fuel pressure

The bypass he has set up is very simple. Just a few tabs with inline fuse for protection and he removed 2 fuses on the RCM and plugged the tabs into the fused side of the block. the new power source is from main fuse block, so it is very easy to unplug no cut wires to worry about. He said he got the hack off this site.

I looked up, Mercedes Swap Shop and SOS to compare pricing options.

I will install the new fuel parts and see where that gets me.
