Fuel pump for classic roadrunner didn't last 50 miles. I suppose 'success' is lucky i didn't eat a $100 wrecker fee. It never started cold without primer until i replaced the new NAPA fuel pump with another new NAPA fuel pump. At least it starts easy now when cold. After doing job twice. The chevy truck has been yard art for two years, as i don't really have time to do every job repeatedly. The store has the used broken part they charger me $300plus for. This isn't a success story, it's a story of failure, no honor or honesty in store, and non-existent quality control.
