fuel pump controller

[cutlasskid]

a few weeks ago we were talking about having problems with the areomotive fuel pumps heating up the fuel to much, and a few of you bought the pump controller to kick down the voltage, well i also bought one and have been thru 2 msd 6AL boxes now and was wondering if any one else has had any of these problems or does msd not make a good box anymore ??? i would not think the wire you run from the tack out could cause this problem but not sure. The first box lasted 10 plus years ,and the second lasted one short drive to the gas station
