FUEL PUMPS, Electric or Mechanical?

[Loose Screw]

On an old 350 that's got Edelbrock carb and intake. Has an electric cobbled in right now and runs just fine but I'm going to have to move it, it's just way to close to the exhaust system and like I said it's "cobbled in" with Rubber gas line. I will be using new rubber gas line for the time being but route it as far away from Hot as I can get it until I have time to study bending stainless steal...anyway, the electric fuel pump that's on there works just fine (so far) but it's noisy as Heck and I'm not real sure about this trucks electrical system......

So, should I put a Mechanical fuel pump, the old noisy electric back on or a New Quiet (reliable) one on there, what do you think?

Thanks!
