Assuming its installed right, up it to a 20A fuse.

i had the same problem, the pump worked fine with the ka then with my redtop it kept blowing the fuse, check the amp of the ka fuse box for the fuel pump, if it matches then find the short

its seems weird but it only does it when im like at a 1/4 of a tank when tank is full its fine

When you are at a quarter tank the fuel pump is no longer completely covered with fuel and can get hot. As electrical connections get hot, they build resistance, and then pull more power. You may want to pull the pump and check all the connections.
