Good quality fuel pump ? or is there any Diffe

If you have not done so already take the time to check your pickup unit in the gas tank to see if the screen is intact. After 40+ years they tend to disappear then nasty stuff gets sucked into your pump which can partially clog it. It happened to me, the new pump only lasted a couple of weeks before I realized what was going on. I ended up replacing the tank, the sending unit and the pump. All is fine now.
