Complete fuel system
Works well, except for if you try to start it 15 minutes or so after you drive it, the starter has to crank a bunch because it has to get fuel back to the carb. Maybe it’s a lack of tuning as well
Next time you think it's going to be hard to restart pull the air cleaner, and look down the carb pump the throttle a couple times
If the accelerator pump shoots fuel it's not a fuel delivery issue.
It might be how you are trying to start it. Are you pumping it 4 or 5 times then cranking?
Typically when hot 1 pump is more than enough.
More could be flooding the intake.
If I drove my dart yesterday 2 pumps the next day and it fired up fine.
Drive, shutoff, 15 minutes later no pumps restart no issue.
The fuel does not get pulled out of the carb, if it is super hot it might boil dry but that's another issue.
As to your question.
Stock will give you the best chance of not having issues, ( electrical, fuel pressure, replacement parts)
BUT...
An EFI tank and quality EFI are very tempting! And that's coming from a stock is the best guy.
