EFI Fuel System

Looking at EFI fuel pump options.. Trying to avoid big money setups. Looking to see if others have went with the inline pump. I know I can draw out without a problem but I'm not sure about the return.. Or is there a returnless option for 42-48 psi? The EFI I'm looking at is a return or returnless and requires 42-48 PSI

I think I've decided that I want to go EFI with my '69 318 Dart. Just enough variables that I think it's what's best for my setup. Currently an Edelbrock and I'm just not a fan of it's quirks... Hard starts due to all the fuel evaporating out after a few days, gives the occasional sputter, erratic idle speeds plus it's an AC car so the idle changes depending on if the AC is on or if the clutch is kicking in or out. I know there's cures to all the mentioned things but it's just a driver and I really like efi.. Not everyone does but I'm a kind of a "you do you" person and not really a purist.

Thanks guys
I considered an Inline, using the stock pickup, but not sure what to do about a return. I'm running a FITECH electric pump in my Hemi swapped A100 Pickup, but I have a fuel cell in thst.. Using the corvette style filter. Works great. Looking at the Aces Killshot efi system. I had a look at the install instructions and it stated 42-48psi min. But doesn't state a max. I'll probably reach out to them and see what max is. They've got a good sale going.. 20% off. I can get the complete kit with distributor fand handheld for complete tuning for less than $850. Pretty clean setup that auto tunes as well.
