Ihave one of those purolator fuel pressure reg you can use until you buy one.There about $50 or you can get the holley regs but there pretty pricey like $150 plus.The standard lines are steel not ally.Most of the bundy ive bought is that copper coated stuff which bends up good.I just did a 3/8" line in mine and put a 1/2" copper line into the tank to supply the lp pump.I was getting enough fuel to feed over 300hp using 5/16" lines and a lp carter..
