Return Fuel Line System
Return Fuel Line System
This might be a dumb question, but if I don't know the answer then it's not a dumb question to me. Anyways I'm getting AEM EMS installed and tuned next Tuesday with 550cc injectors and I was wondering is there a need to still do a return fuel line system conversion? Thanks for your input!
Nope, not necesarry. But, it depends on how much power you want to make. The return line itself isn't going to benefit you by itself. The only thing beneficial is that you can put in an adjustable fuel pressure regulator to raise fuel pressure. But if you're making 300 whp, 45 psi with 550's should be more than fine.
