Ditch the 5/8th line,its too big,on accelleration it may be hindering fuel flow......

when the cars moving forward the fuel may be moving backwards due to the larger size of the hose reducing pressure, but hey, to each their own, 5/8s line on a 10.90 car? new to me.....

A 5/8 fuel line running from the back to the front of the car has a lot of fuel in it that under hard acceleration the weight of the fuel will make the fuel pump see more pressure than is at the regulator.
