EFI conversion fuel delivery?

[Patman]

85 K10 383 Vortec Stroker - Converting to Atomic EFI  - Fuel delivery questions:

I in unfamiliar territory here. I've eliminated my mechanical fuel pump and am trying to determine the best way to get fuel delivered. The options I'm aware of are:

1. Keep my original tanks but add an in-tank fuel pump that goes to a sump that then goes to the fuel rail/tbi unit


2. Get new tanks/pumps that are designed for EFI conversions

what other options are out there? im sure im missing something. Any help is appreciated. Thanks!

If I were to do the tank set-up, I'd be converting to the big, rear-mount single tank.  Everything would be clean and new then.  Just me though...

Options:

#1. Install a TBI in-tank fuel sender unit and pump, or any aftermarket in-tank pump setup. Make sure the pump meets your Atomic psi requirements. You might need a fuel return line too. Check install instructions.

#2. Leave your carb in-tank fuel sender units and put mechanical pump on the block. Then install a fuel sump and use the mechanical pump to move fuel from tanks to sump where it is then pressurized by electrical pump to TBI unit. Might still need return line, check Atomic.

Some guys go with a higher pressure in-line pump not in the fuel tank or sump, but I don't recommend those because they are notoriously loud and prone to frequent failure.

Hey Shifty, I've considered that but I like the larger capacity dual tank set up. I'll be using it for some hauling so the extra fuel will be nice to have.

Mr. Diesel, Im leaning towards option 1. Found a company that makes after market tanks with sending/pump units that are pre plumbed for return lines. Makes for a clean install for sure. Its a little pricy so I was looking for a reasonable plan b. Still, I dont mind spending the extra $ for ease of installation.

Gotcha!  Still, even if you're going to get 8mpg, that's still over 200 miles...
