Personally i dont think a hot 202 especially running a carbie setup is going to use more fuel than the factory line can supply. a low pressure electric fuel pump could help.
So in essence upgrading your fuel line is a waste of money.
Ding Ding, wrong
3/8 wont be enough if you intend to rev it hard.
EFI is under 300 PSI pressure, different kettle of fish compared to 5 pounds pressure.
You need large diameter fuel hose and it also acts as a resivour.
With my old setup running 45DCOE webers i use to run 1/2 inch inside diameter 5/8 outer roughly fibreglass re-enforced Fuel hose.
Same as this stuff.
Screw it into chasis rails with these under car
These are easier to use as they chasis rails are not real tall.
Mount it to the side of the rail not the bottom where it can get crushed, lol
You will need a hole punch to go thru the boot as its best to mount a Holley Blue fuel pump in the boot.
Use special plastic grommets thru the floor of the boot, they need to be strong as to stop and sharp edges rubbing thru the hose.
You would also need to drill a hole in your fuel tank and silver solder a brass tube into it that ends up down the back end of the bottom of the tank for a fuel pickup as the stock pickup will not flow enough either.
Webers do have there own internal fuel guaze filters but i reccomend a morros fuel filter inline between the tank and the fuel pump.
Sorry dont have any picture of my boot setup but here is one of the Webers in the bay, good old days.
This thing could run 12.7 all day down the quarter mile even with a big heavy 9 inch diff in the rear.
