My number 3 (I guess it's #3, it's the one that stands taller than the others) injector is leaking. It's not terrible but I'd rather fix it. I want to eventually put nozzles on, but I'm afraid of breaking stuff in the process, which has happened every time I try to fix something on this car. Should I just fix the leak, leave it, or go ahead and do nozzles too? How involved is that? Having trouble finding anything on ahus specifically. Thanks for yalls help.
