New fuel pump in 01 blazer making humming noise
\015 I just changed the fuel pump and now its making a weird humming noise. Is the new fuel pump bad or did i not do something. All the lines are hooked up right I can't figure it out.\015
No Fuel Pumps do Humbbbb, and some loudly, although you probably left the rubber/insulator for noise absorbtion off the pump. The new ones usually dont come with this, unless you get the whole assembley. It's just a rubber piece that wraps around the pump motor nicely and ablorbs that Hummbbbb.. Time to drop the tank again. I hate when I do that..
