i am pretty much finished installing my hrc stage 1. battery is hooked back up and we checked for fuel leaks...and sure enough there is a leak on the fuel filter. the leak is on the side where there is a 3/4 in hex...i slid 2 copper washers over the bolt...one on each side of the fuel line. i tightened it as much as i could...i have no clue why it is leaking...has anyone had a similar problem? anyone know what i can do?? tia
