Question about crossfeed and mk3 service bay

[Jesusthebird]

Been trying to figure out how to get my service bay to lock being crossfeed disabled. I have a few small LF/O tanks radially attched inside with a universal storage fuel cell. Id like to keep that fuel reserved for the fuel cell. But cant seem to figure out how to make sure my engines dont draw fuel from those tanks. Of course id prefer no part adding(supprisingly mk3 doesnt even have an inline decoupler?)...maybe a mm patch i can setup manually?? Or clone the part and add a module node maybe?

Im not at home rn. I think i have the coupler mod installed(for built in couplers for tanks) but i dont think that gives crossfeed rules to the service bay.

 

Any ideas?? Thanks

A screenshot of yours setup would be helpful.
Put a decouper between fuel tank and the hull and attach fuel cell directly to the fuel tank.
