Have not had a lot of time for the car but I have designing my fuel system and because this is a forum where you come up with and share ideas I that I would post my idea of a good fuel system. I have ordered the parts to, but itīs a long road to go before I can install it.
Here is a drawing of what i am going fore.

It starts with a Tank inc. PA-4 pump that is mounted in the original tank, do not what a external pump that goes ti-ti-ti-ti as you drive along.
Then there is some braided hose to a Corvette filter/regulator, this sits in the back of the car infront of the tank.
From the filter/regulator I have a hardline that goes to the front, this to not have a dipp in the fuel pressure.
In the engine room it again changes to braided hose before it is connected to the original fuel rail.
All the fittings are AN and the ones to the rail and filter regulator are "specially" made fore this purpose.
This is in my opinion the cheapest way to go, and it is not a bad way. What do you think?
