On both sides of the tub 5/32" brass tubing is added passing thru tub wall into each fuel compartment, one for pipe pressure in & one on the other side for fuel out to third channel needle. The tubes have DuBru fuel barbs soldered on each end and are custom bent & 'glassed in place with 3 layers of 1/2 ounce cloth. This allows a much tighter turn into the fuel compartments than you could get passing just fuel line thru not to mention they pass thru behind the front radio box area.
