Please help with the gasoline pump

I have an universal electric gasoline pump I present problem, I was not filling the gasoline filter, with the engine failure (it turns off) it changes it and follow the problem. Media the voltage that enters the pump with the engine on and marks 14.67 volt the voltage that marks the battery that is fine because the pump says that it is 12volt¡ and I also do not know if it is normal for the pump to hot?

The bomb is eating by a relay over it and tell me

Hojo Cesar The filters are never filled completely, so the fault can be elsewhere, tell us as is the fault to help you

Hi Karma, it seemed that he was going to pay for fast as if it were running (he made a very fast change) when I arrive at the house, I realized that the filter was dry and the pump is very hot and it sounded very rare, I did not do it anymore, check the pipe system that goes from the tank the carburetor and I saw that it does not have a return is condemned, how do I install it, do you have to do it? Can that be damaging the pump?
Thank you really for the answer!

Not for nothing more, there when the fault was presented that fuse was very hot! Help me with this crab
