Re: Noisy fuel pump (still!) (and again!)

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.
