The issue = with=20 vacuuming a sealed tank from the filler hole is that once you stick a = big=20 sucking hose in the filler hole what you will get is a lot of = in-rushing air=20 around the nozzle that will blow bits of debris to the four corners of = your=20 tank. The air being sucked from the tank is replaced by air coming in = the=20 filler hole.  So, if you use a small hose =96 say =BD=94 ID then = the amount and=20 velocity of in-rushing air won=92t be as great and won=92t disturb any = debris that=20 might be near the filler hole. Takes a long time to vacuum the tank = with a =BD=94=20 ID hose =96 but it=92s the only way to do the job=20 effectively.
