There could be several reasons for the fuel to get hot. 1) You are in a hot climate 2) there is a problem with the pressure regulater set too high causing the fuel to heat up as it circulates in the system. 3) when the tank is low the fuel will get hotter as there is less fuel to dissapate the heat into. 4) air leak in the pick-up hose. To solve the heat and possibly the pump noise problem at the same time would be to try to keep more fuel in the tank. When the pump is submerged in fuel it is much quieter and will run cooler. If you think the filters are a restriction just try running without them for a short time and see if things are better. It is very easy when installing the pump into the tank to slighly turn it causing the pick-up line to kink, this could happen even with a spring inside the hose so be very careful as you install the pump. A pinhole or tear in the hose will cause an air leak causing a noisy pump and probably contributing to hotter than normal fuel. If these problems go away as you keep the tank full then you know what you will have to do.
