[i have crabs]

just the insides of the old pump looked a little grungie but i dont know if those parts even touch water anyway, it seems strange to me that the pump would burn out. if those pumps have any oil in them either for cooling or lube i would assume thier is a chance that something from the pump was leakin in the water since the pump was leaking water almost from the start and then al of a sudden it fries on you.

i didnt really look but i assume you have been keeping an eye on the temperature
