I installed new heads couple of days ago and car was running great,now I am blowing fuel pump fuses!As soon as i put it in and turn the ignition on it blows.I have an adjustble fuel pump regulator, could i have the pressure set too low or high causing this problem?Fuel pump sounded fine I ran a jumper wire across the fuse hole and worked and fired up,but I was afraid to drive it like this.Please help!
