Have and aftermarket fuel rail that i need to run some lines to. have an 2008 pump that has 5/16 out of the tank and 3/8 return. going to run AN fittings and want to know if i can come off the 5/16 with a quick disconnect and then right away enlarge to -6AN(3/8) into the fuel rail and then run -6AN back into tank after rail. would run -4AN before fuel rail but that is 1/4 and don't know if that slight restriction is bad. So though maybe just enlargeing is ok??????????
