 You guys helped me a couple years ago. I had a fuel pump issue. I put a new fuel pump. It's an 06 Ram with 3.7. And, of course, there's a cheap pump. And you suggested the inline check valve. That worked great. Well, little by little, I started having multiple misfires over the last several months. I chased it down to number two and number four. I've replaced the valve lash.
