Sounds like a good approach if you have the money. Glad you like your system!Once again I will suggest going with the Edelbrock returnless fuel pump system.
1) The surge tank is built into the system
2) The adjustable regulator is built into the pump, the filter just goes inline between the pump and the rail
3) You dead end the fuel rail, no need to run a return line to the tank
4) The high pressure pump only needs to pressurize about 2' of fuel line and the rail itself, no need for it to pump gallons and gallons in a big circle back to your tank and back to the fuel rail and back to your tank and........etc.
5) A low pressure pump does the grunt work of bringing the fuel forward from the tank
6) The high pressure pump is emersed in fuel, so it is constantly cooled
7) The system can handle 700hp worth of fuel consumption
8) You mount the main pump and surge tank combo somewhere in your engine compartment or, in our GT's, in front of the radiator somewhere for easy accessibility and, if in front of the radiator, additional cooling
9) It is quieter than any electric fuel pump, carb or FI, that I have ever experienced in my modern cars or the one Opel I have it on at the moment
10) No messing around with your 50 year old tank and running a return fuel line inside your passenger compartment. You do run a vent return line to one of the tank's vent outlets
Why would you get vapor lock in an FI system? The fuel doesn't sit in a reservoir, where it can get baked to the boiling point by exhaust heat, like our carb systems do. If you route your fuel line in front of the radiator, then to the carb or FI system, then it's not subject to any heat. Maybe, only a big fuel pump mounted at the back of your car shoving all the gas in your car in a big circle, non-stop, would heat up your fuel enough to get vapor lock.
I've worked in industry my whole life and I have never seen any hydraulic pumping system that requires a large amount of fluid to be pumped in a giant circle, non-stop, to supply a tiny amount of usage. The water in your house doesn't work that way. Hydraulics only activate the pump when needed. Air conditioners only pump their fluid when the compressor turns on. The list goes on. I can't think of any fluid system that needs to supply a very small amount of fluid to an outlet that works the way old school car fuel pumps work.
My new car will be getting another Edelbrock system and this time I will try mounting it somewhere in front of the radiator, maybe on the horn rail or maybe below or next to the master cylinder.
Personally, I am going to put that $500 towards the Holley Terminator X ECU. I choose to save money where I can design and fabricate. But I can’t design and fabricate an easy to use ECU operating system.
that said, I like the idea of being able to install/ upgrade the fuel system and still run my carb for a season until I have all of EFI components ready to install if the edlebrock system can be turned down to 4 psI. That way I can install my fuel pump block off plate and trigger wheel holder.
