I wouldn't. I rebuilt a fuel system recently where the owner had used silicone at the hose connections. Little pieces of cured silicone got into the fuel system and found their way into the inlet of the Racors reducing the flow enough that you could still bleed the system but not run it fully loaded. We replaced all the hose from the tank to the engine filters.
