regardless of mounts there's movement and pleanty of vibration there. That little pinch makes a 3/8 fuel line flow like a 1/8" line. You've do better to have a straight peice of steel line to the fenderwell, then a 90° in it, so the rubbr is a straight shot to the carb line. Anything's better than what you have there...
That setup wouldn,t pass tech up here.If you ever threw the alt belt,you,d have lots of gas pumping everywhere.Maybe move your regulator back 12 inches.Just sayin...Good luck.:D
As mentioned,the pinched rubber fuel line is no good, and worse than that,is your steel fuel line with the 2 90deg bends. That's killing you. Back the reg up,and come straight across to the carb with your line.
