I’ve noticed rubber products, particularly those exposed to heat or UV rays, have been going down in quality and durability for decades now. Things like valve cover grommets, wiper blades, pump diaphragms, they just don’t make them like they used to.
A mechanical fuel pump is on my shopping list so I’m taking notes. Seriously considering going to Pick-a-Part for a good used pump instead of a new one. I always used to run Carter Super pumps with good success but sounds like maybe their time in the limelight has faded. Used ones can be a gamble too… [emoji2369]
