Okay,
I have read extensively on MUD about fuel evaporative separators, and the charcoal canisters. But all these discussions have been with reference to carbuerated engines. I have a 1/79 FJ40 with a 350 conversion that I plan on upgrading with EFI.
Do I still need the separator, and the charcoal canister with fuel injection, or does it all go away? I recognize that I will have a need for a return line to the tank, and that all the fuel in the system will be running at a higher pressure, but I am still not sure I understand whether or not the charcoal canister will still be a requirement to eliminate vapor smells.
Furthermore, if the charcoal canister IS still needed, where will the output route to on a fuel injected system. For the standard carbuerated system, I have read that the fuel separator routes to the canister, and the canister routes to the carb. So how would this all work for fuel injection?
Be gentle, I am just learning the basics for all of this emissions stuff, and have quite a bit of research and learning to do before I take on this task later in the year...(maybe next year)
Thanks,
Chris
