Re: fuel pump

[dherv10@xxxx]

Christian, If the fuse melts down, there is a reason for it. The fuel 
pump is an electrical motor. If it's old and getting wore out it will 
draw more current and cause more damage to the electrical system. If 
the fuel pump has to work harder getting the gas maby due to a 
partially stopped up screen, then again it will draw more current and 
burn out the fuses and possibilty burn the RPM/fuel pump relay 
contacts. Putting in a higher fuse will always add to the problem. 
Replace the fuse with the correct one make sure all wires are 
connected firmily and see what happens. If it burns again, then the 
pump may be defective..
