I have a Holley blue elec. fuel pump. It was loud for about 5 months of use. Now it's not as loud but gets hot and shuts off after about 20 min. of driving. Is this normal of these pumps life cycle ? Just need some info. and maybe a better idea or pump. Route of delivery is tank rubber 3/8 line small filter rubber line pump rubber line big fram filter s.s. braided line then weber carb.
