92stroker

I have replaced the fuel pump 2x recently. The first was a POS from AutoZone, the second an OEM. They both started making buzzing noises. The first one got to the point that it failed completely. When first fired up it runs normally, then after the engine gets hot the buzzing starts. It's loud enough to be heard inside or outside the Jeep, and from a good distance! If I shut off the engine and wait a few seconds, then restart the engine, the buzzing stops for a short time (maybe 3-4 minutes). The frequency becomes shorter and shorter between shut off/restarts until it is constant.
Background: I've had an ongoing heat issue. (See previous lengthy thread naxja.org/forum/showthread.php?t=91422&highlight) The Jeep is a 92, stroker. #24 injectors, header, bored throttle body and pacer...etc...etc.
Question: Could this be related to the overheating issue? Could the return line to the pump be overheating causing the pumps to fail? What could cause this, heat transfer from the engine? I've started down this road due to the fact that I had the return line fail. It failed at the plastic section between the 2 metal lines that runs up by the firewall. From the look of the hole, it appears that it failed from the inside out and sort of looks melted. Needless to say I'm scared $*#!less to drive the thing!
Could this be happening? Are there other issues that could be heating up the line, or am I barking up the wrong tree altogether?
