Upper wing tank into lower tank Pitts plumbing ?

[cgzro]

My certified Pitts came with a 337 smoke system from the upper tank. I'm thinking of getting rid of it and going back to the original upper tank as fuel which can then drain into the lower tank but I have no documentation on this configuration and its not described in the parts diagrams for the plane.

Does anybody have the parts diagrams etc. for this configuration (certified or not) or pictures of their installation in a Pitts?

Thanks

Peter
