Article doesn't discuss fuel mileage or general street performance related to ease of starting and self tuning. They installed it on a performance engine focusing on torque and HP...EFI in general just makes starting and driving easier and more enjoyable.

Looking at the comparison between Carburetor and the EFI in that article the EFI looks to perform better at higher rpm's

Over the weekend I got my fuel lines ran and my tank mounted back in the car with the new fuel pump wired .I'll finish up running the rest of the wiring this week and when my new EFI arrives I'll be ready to just drop it in and hook it and tune and go for a ride.

62131  make sure you set the electric fuel pump into the ignition switch.so if you have to kill it at any time its simple shut the key off.I set mine on ACC.so when i turn the key to the first notch the pump comes on when the pressure is sufficient the pump shuts off and its time to start  vette59jdwl

My plan is to install a three terminal oil pressure switch, wire it thru the n/c  while starting and the n/o will close while in the run position keeping power to the pump, if I should ever get a leak on the pressure line the engine should stall and kill the power to the pump. I think I said that right.

 I was cleaning my tank from the cutting and welding that was done. I vacuumed the tank out wiped it down and then dropped a couple of magnets in and poured in some mineral sprits and sloshed that around picking up any metal particles on the magnets that I had missed from vacuuming and wiping, had to clean magnets several times to remove all particles. After I quit picking up any metal particles I removed the mineral sprits and I just left the magnets in the tank as an added precaution.
 I ran new 3/8's aluminum supply and return lines, after all my fittings were installed and before I connect my flexible lines I blew air thru the lines to remove any aluminum particles that might had fallen in while de burring the ends that I cut.
The question is would you run fuel thru them or is blowing them out sufficient? The magnets wont help here.

That's how the stock TPI engines are wired.

Personally from what you did so far...I would think you are good to go! Fill it up and start it. Does the kit come with an inline filter?

My EFI kit will not be here for another week, they have some parts on back order. No it does not come with an inline filter but I purchased one like what's in the complete kit from our local parts house

Guess you can get the O2 bung welded in while waiting.
