Great article. Michael Harding of Street Legal TV has done much along the fuel tank line. He has an in tank system on his 65 Ply "Track attack" car. That car has all the goodies. I can't believe he hasn't stepped up to a bigger cam. He's still using the 264 hot street cam in his 318 with his dual quad Fast EZ EFI. He is planning to change to a 360 in the future.
My thoughts on advantages of the fuel pump in the tank is to overcome some of the problems caused by new fuels. Access to our tanks is nothing more than one strap holding it in place. Here is some thought to start with.Nick
