  1. I want to thank HT10XTPBads for his post...I just purchased a lightly used 2020 Hd10 last week that only had about 23 hours on it. After the first couple of days, it started sputtering a little when I first took off from a stop, as if it wasn't getting enough gas. Once I started going it seemed fine. Then the next day it was a little harder to start, would turn over a few more times before it came on. Also started noticing that it would sputter at higher speeds, not just from a stop....Longer story short, I found this thread and started looking into it. I took out the pump and replaced the o-ring with one I found in a variety pack at Auto Zone. Runs perfect now! That O-ring is obviously a very critical part of the fuel pump and if it does not have a tight seal then you won't get the proper fuel psi.
