EFI Fuel Pumps

Thinking about an EFI setup. And as we all know the fuel system is the key.

SO my questions are: In tank VS in line. Best brands/setups. Return or no return.

Im thinking Aeromotive Phantom 200 and MSD Atomic.

Phantom 200 Stealth Fuel System – Aeromotive, Inc

Although, the Holley has a higher flow rate for less money.

Just looking for some open dialogue.
