Do you have to manually switch tanks? Tell me that they have an automated system.
I have 5 sumps too : ( One for each wing tank, two under the fuselage (it could have been one) and one at the engine. I typically just check the two under the fuselage and engine sump because the engine sump can catch a cup of water or so.
Yep - left, right and both ... on the other a/c you have five for each wing, and lower sump ....
