Is your fuel system returnless? If so you could just un-bolt the Fuel Pressure Sensor(it's not really a regulator) from the rail and slide it out. If it is the return style, you then have two of these lines coming off the rail and would then require a special disconnect tool(the second line has no bolts). They are very inexpensive, a cheap one is made by Lisle Corp. and sells for under $15. It is probably available from any quality auto parts store.
