you need a 1/8 bsp to npt adapter, then screw in a 1/8 npt flexible braided line with the adapter to where the stock sending unit is. secure the other end of the flexible line to the firewall and use a T. one side of the T gets the stock sending unit the other gets the new pressure sending unit. if you screw the T directly to the block its too heavy and the block will crack.
