Fuel pump question
My fuel pump is somewhat loud. From the inside, you can hear it quite well, like a constant pitch (buzz, whatever). I was told that it happens, especially on the Jeep Wranglers, and that I shouldn't be concerned as long as it works fine. Avoid riding on low gas level in the tank, and that's it. I was also told that it happens due to the pump not being so firmly connected, so it vibrates a bit, etc.
Is that true? Is the gas pump on the outside of the tank, somewhere that can be reasonably easy accessible, so I could get to it & tighten it (or put some silicone around) or something similar?
