Carb to EFI
To start, sorry for the long post. I will ask my questions starting from the fuel tank to the engine. I have an '84 Z28 Camaro with a 350.
I recently won an Edelbrock EFI system, part number 3220. I am trying to figure out the best way to adapt my stock fuel system to work with this kit.
I plan on using the stock fuel tank with a fuel pump from a fuel injection third gen camaro.
What year and model of Camaro could I use to order a fuel pump for?
I understand that I will have to change the section of hose from the fuel tank to the fuel line, to a flared style connection to hold the new pressure.
Will the stock steel fuel lines hold up to the pressures?
Will I need a fuel regulator? If so would return style be the best way to go?
Thank you for your help and time

Re: Carb to EFI
Another possibility is an external pump, using the original tank fuel pickup, gauge sender, and filter sock. It's been done hundreds (perhaps thousands) of times with EFI conversions. This is just one option:
The original steel fuel lines are capable of sustaining the pressure of an EFI system so long as they are in good condition. Of course, the flexible lines will need to be changed to something suitable for the higher pressure.
I am unsure of the Edelbrock system requires a separate regulator, but suspect that it does. An external regulator with a return line is preferable since it assures fuel flow through the pump (for cooling) and helps prevent vapor lock in the fuel lines, also due to the fact that cooler fuel is constantly flowing. It may be suitable to use one of the original fuel vapor lines to the fuel tank as a fuel return line.

Re: Carb to EFI
Because I had access to salvage cars when I did more EFI work,
Removing the fuel lines from a third gen ( they may readily be reproduced now too ) was the easiest way for me to get the Saginaw fittings for higher pressure.
The carb models tend to have low pressure fittings and while EFI clamps can be used with EFI hose, I would suggest flaring and using fittings for high pressure, or what I mentioned above. An 87 would have the high pressure EFI system, with lo pressure booster pump, even when 4bbl. I am pretty sure an 84 would not.
