Last time I had this problem, it was a 1970 VW Transporter with a 6-cyl
Corvair engine/trans. I removed the tank, added a jarful of old
ball-bearings and shook the crap out of the tank to remove any scale
present, etched it with muriatic acid, washed it out and dried it in the
sun and then applied a liquid tank sealer I obtained from the local
aircraft spares company. I used the kind that also is impervious to
alcohol, since it's sometimes added to petrol in this local area. The
liquid is poured in, all vents and openings sealed and then the tank is
tumbled and shaken and turned over to coat the whole inside of the tank;
then one of the openings is uncovered and the excess is poured out and
saved. It did a perfect job; never had a fuel-flow problem with that
vehicle again. The whole operation cost me less than US$50.
