64 dart convert to EFI

Thanks all for your replies, originally the shop rebuilt the carb (along w extensive overhaul) — they test drove it 100 mi successfully before a sputtering issue back at the shop. They foresee future carb issues and recommended EFI for peace of mind long term.
I do not have the knowledge, space or time to do this myself, but I have budgeted to get this Dart to daily driver standard. I plan to keep it long term, drive it often in season, and to be content with this one classic.
I am computer competent so would be comfortable with that aspect of learning and maintenance once installed.
I had read positive Holley Sniper reviews here and entered my vehicle info on their site which lead me to their Holley Sniper EFI Self-Tuning Master Kit (4bbl). Unit is expensive and backordered, but is this what I’m looking for?
And noted on the supply and return lines for the fuel tank, is there a recommended brand, compatible with the Holley Sniper and my model year?
Appreciate everyones replies and advice
