I'm Curretnly in the process of installing my eldelbrock nitrous system. The instructions are telling me to unhook the hose that conects to the fuel presure regulator. First off i'm not sure which side of the regulator i'm supposed to unhook the hose from(one side, the right side,says HIGH PRESURE FUEL the other just has numbers and the ford symbol). I decided to go with the left side which has the ford symbol on it. But when I tryed to take it off its like its been attached with some teflon glue which doesnt surprise me. Is there an easy way to get that off? Any addvice about the elelbrock nitrous system would be appreciated.
