    Brad I marked the fill flange and body with a magic marker, went back in with no problem!
    Many thanks for the learned follow-up!

    Be aware that there are 2 possible clockings of the fuel filler. Only one way as installed will allow the filler CAP "Ears" to be aligned so it doesn't hit the gas door when closed. Also check the new production replacements, as the clocking will have to be changed to accommodate the new caps. Also remember that the caps turn 90 degrees when fully seated so allow for that.

    So as Paul Harvey would say.................and that's the story..............................turns out the Ideal hose clamps loosened up to the point that they were just laying on the hose..........and I was foolish 20 years ago because I utilized a hose that was for boat use, rubber with steel cords running through it.......it is a wonder the clamps were able to get any kind of "bite" on the hose. Buttoned everything up and utilized 3M calk to seal the firewall........it's all good!!

    Denny you mean the passenger side? That is the vent line from the gas tank into the sail panel then down and out on the rear passenger side.
    Last year I replaced the entire steel gas and return line with Cunifer line, additionally I utilized fuel injection spec house for ever rubber part of the gas system. My leak is at the rear drivers side bottom Q panel

    Years ago I was dripping gas. It was the gasline that loops over the left rear fender well. Gas line is inside of rubber hose and had rusted out. Replaced that section of line and no more problems. This was 43 years ago

    No - just tighten the band clamps firmly. Any gasket cement at that location runs the risk of finding its way into the fuel stream and causing stickiness in the carburetor IMHO.

    Yes. That is the preferred approach. Once the tank is exposed loosen the 2 band clamps on the "hose" and remove the galvanized fill port, followed by the hose. Assemble in the reverse order, locate the hose mid-point in the gap between port and tank neck and tighten the band clamps. If the alignment of fill port and tank neck is off, then you may have to loosen the tank to body band clamps and move the tank laterally to correct the alignment. Flow into the tank should be straight down with no distortion of the "hose". The most time consuming part of the process is accessing the tank - seat bottom, back and compartment panel removal.
    Any gasket cement needed on the galvanized fill port neck?........or just place the gasket "naked"?

    Many thanks for the fast response! It has been about 20 years since I pulled the tank, and did not remember exactly how to go about the process...LOL there is always something to do on an Avanti.............has to be, after all I have owned her since she was three years old:-).....I do laugh when non car folks comment about how good the car is for its age.........they just have no clue as to the time effort and cash it takes over many years to keep these cars on the road and safe.

    Gentlemen, before I begin to remove the rear interior, can you advise the order of removal of the gas tank filler hose?..........does the galvanized fill neck have to be removed to fit the new rubber hose on the gas tank neck? Just want to be prepared for the 'deed' Thanks to all for the assistance.

    What you call a rubber collar, is that the rubber "hose" that connects the neck of the gas tank to the metal collar behind the gas door on the q-panel?

    Years ago when I had the tank out i had the radiator shop tack pennies on top of every spot weld. What is the rubber collar?.....are you speaking ``of p/n 1554674 gasket?

    The fill rubber collar may be a bit loose or degraded, allowing a bit of leakage during the fill operation. Best to remove the back seat panel and have a look. Also check the tank for evidence of fuel seepage on the end plates and spot rivets while you are at it.

    Alan I removed the drain fitting when I replaced all the gas line. The gas line was all dry, just this crazy tiny leak under the Q-panel lip. As I said it stopped leaking after about 4 minutes.
