Magnum motor with Mechanical fuel pump ?

its deff easier, but those damn electric pumps are loud as hell and always seem to burn up. I went through two of them in a year on my 70 dart and i went through 6 of them in a year on my 67 impala.
Might be a case of they dont make them like they used to. Were they re buildable?
Was it the gas? I was thinking the fuel for some, a friend kept having needle seat failures in his holley and went to fi tech. Lives near the mountains.
I have a holley red pump I used for 4 yrs straight 'daily driver' , it did have a little buzz sound being it was mounted to the frame via thin rubber gasket they give you.. but I bet a well thought bracket with rubber isolator grommets would cure that.
