Yes i can hear mine running but only because my truck is almost silent. I have a huge muffler from a duramax van on my truck and if the truck stalled at a light you wouldn’t know it until you went to let the clutch out and it didn’t move. Its that quiet. I have very good hearing too. Im very used to hearing fuel pumps though so its nothing odd to me. Im used to driving around in fast cars with fuel pumps that sound like 3 blenders running full tilt. In tank pumps are always quieter but this truck was built for zero performance and the external pump was just too EASY I couldn’t not do it. 🤣
