When to replace Fuel Injectors?
I have a leak in I think the fuel injector return lines and need to relace the o rings, return lines, etc to hopefully stop the leaks. I plan on getting the kit for this. Should I also relace the injectors while I am at it? It is a 1994 F350 7.3 Non turbo with 137k on it with original fuel injectors. How do you know when it is time to replace the fuel injectors?
