B 17s had them so i am thinking mainly bombers would have them titian
Why do you think the B-17 was able to dump fuel?
Based on my knowledge of the Fortress gained while flying the airplane for two years I can assure you the B-17 did NOT have the ability to dump fuel in flight. Sheesh, you can't even transfer fuel between tanks in the same wing, you have to first move the fuel to the opposite wing then back to where you wanted it in the beginning.
