School me on a good fuel system

[anguilla1980]

Fuel systems are my weak point. I'm going to buying this Holley Terminator EFI in the coming weeks: https://www.holley.com/products/fuel.../parts/550-441

But the fuel pump their sell with their tank doesn't exactly look top-notch: https://www.holley.com/products/fuel...s/parts/19-404


I would like to run a proper in-tank setup and I don't mind a new baffled fuel tank either to support it rather than cutting into my existing one.

I think I'd like to run -8AN black nylon carbon impregnated PTFE lines, of course keeping a return line as I'm concerned with fuel temps out here in the CA desert. Also on the theme of temps, I want something that is electronically variable based on demand as it's my understanding that a fuel pump running at full power will only serve to heat up my fuel needlessly.

It only needs to support 650HP, but it's important to me that the fuel system is ROCK solid with more than enough juice to get the job done and minimal fluctuations in pressure.



I know there are some insane custom setups out there but as you can see, for just 650HP and doing HPDEs and road courses, I also know there are plenty of awesome aftermarket kits that should get the job done no sweat. I don't want over build it and waste money spent better elsewhere, but I also want to find the right balance so as not to be compromising anything either. For example, maybe a -6AN is plenty large for me and no need to go with a -8AN setup. I have no clue.


Please post up your suggestions or suggested vendors to reach out to on this.

Thanks!
