I'm planning on upgrading the fuel system on my 73 Cuda from the stock 5/16 inch fuel line and mechanical fuel pump to an in-tank electric pump. The tank I'm looking at is the Spectra Premium CR8CFI tank with an internal Walbro 255 lph pump (link: https://ecat.spectrapremium.com/products/CR8CFI). I'll also install 3/8 inch feed and return lines with a bypass pressure regulator. I'm thinking a regulator like this should work well: Edelbrock 174053 (link: https://www.edelbrock.com/carburete...ator-180-gph-in-black-finish-174053.html).

Looking at the flow curves of the pump, I know that I'll be bypassing much of the flow, because I only need 5-7 PSI outlet pressure (instead of around 50 PSI for EFI). Here's a link to the flow curves: https://walbrofuelpumps.com/universal-in-tank-fuel-pumps.html. My engine puts out 510 flywheel HP, so the flow should be more than adequate.

Given that, here's my question/concern: A) Has anyone done this on their car? B) How is the fuel pump holding up?
