Every two days we have to replace the main fuse of the pump because its is burning. This fuse is 30 A and it's located near of truck batteries. Any suggestions? 

The main fuse should be a 80A fusable link, inside a small electrcial panel next to the truck batteries;

What year and dose it have a duvac on it

it is 2011.

There is a ground and a power wire that runs from the battery box, down the frame rail, to the computer at the back of the pump.  Sometimes a rock or something gets lodged between the water box and the wiring harness rubbing off the insulation and causes a short.  If that is the case it is very easy to run another ground and power wire to the back.  Be sure to use a large enough gauge wire and use a protective conduit.

Please feel free to contact me with the serial number and we can discuss your issue.
