Default Feed the front of the rails or the back???

Does anyone know if it matters if you put the feed at the front of the rails or feed the back and return thru the front????

I had heard on high HP cars that see some big G numbers when launching and on acceleration that you'll make the fuel pump work harder if you feed the back of the rails since you are having the push the fuel against gravity HOWEVER that doesn't make a whole lot of sense since you're doing that anyway to get the fuel to the rails in the first place from the tank.... So if it matters i'd like to hear some opinions.....

I don't think it matters. ECS feeds their 9sec race car fuel rails from the rear...

I agree that it doesn't matter.I like feeding the rear. Our 7 second cars get fed from the rear (1.1 60')

for your lines, do you feed the single side rear and loop the front around from driver's side to passenger side?

do you split it and feed both sides of the rear and blocked at the ends?

or do you split it and feed both sides of the rear and have the front looped together almost as if a complete circle?

any suggestions on that?
