The "Large Fuel Tank" takes a few shells to blow up, but I prefer to use the Oerlikon or Bofors AA gun on them to conserve ammo.

Some data that might help:

1. Large Fuel Tanks have 100 hit points each.
2. Your deck gun does 25 to 40 HP per hit (depending on how far you've upgraded it).
3. The M2 Browning AA gun does 2 HP per hit.
4. The Oerlikon AA guns do 7.5 HP per hit.
5. The Bofors 40mm AA gun does 18 HP per hit.
