Rv-4 smoke oil tank

[Taltruda]

Anybody have any good pictures of a smoke oil tank in the baggage compartment on the RV-4? I might end up making a custom one, and wanted ideas for perhaps an external fill port too.. either that or a check-valve and a reversing relay on the oil pump..I don’t know if my pump can reverse though..

Here is my 3.5 gal in the RV4 baggage compartment

I installed mine (3.5 gal Smokingairplanes) system in my baggage floor. I made some attach angles and stiffened the floor with apiece of .050" where the tanks sits. Takes 5 minutes to disconnect and pull tank out if I need to. I can still put plenty of travel bags on top if going somewhere. If I'm flying with full oil and a PAX, I like having full fuel for CG purpose, but solo its a non-factor. I put the 3 position switch/light just forward of the throttle with a momentary button in the throttle grip.
