Don RE: packing - you may have too much in the stuffing box. Our 34 has a 1 inch shaft. We use 3/16 Teflon packing (much better than flax). 3 strands cut at 45 degrees with joints staggered. Works just fine. Takes a few adjustments to get the correct drip - none when at rest a few drops per minute when running. So we have 9/16 total packing. If you have 4 strands of 1/4 inch that is a full one inch - too much IMHO. Also most important to ensure you have all the old packing in fact removed. We use a 1 1/2 inch screw and screw it into each strand and it easily is removed. You know you have it all out if the nut moves freely around the shaft at various angles.
RE: air - have you checked the shut off valve on the inlet? Maybe needs to be removed and rebedded?? Same thing on the filter fittings. How about the inlet tube inside the tank where it mates to the fitting? Yes a low fuel level in the tank will allow air in if heeled to starboard as the inlet is on the port side.
