Q: Will the Tempest AA473 Oil Drain Tool work on a Champion filter?
Yes, this will work on Tempest, Champion, and other 3-1/2" diameter filters.
Q: Does vertically mounted mean that the filter threads up into the engine? I have a Lycoming io360 and it screws in horizontal to the back of the engine.
Per Vendor: Yes, it will work on different filters and positions. So it can work in the horizontal and vertical position.
Q: What is the max diameter filter it will fit around?
Approx max dia. 4 inches.
Q: Will the Tempest AA473 work on an RV10? Any purchasers of RV10s comment?
We do not have an aircraft application. It will work with all Tempest, Champion, and 3-1/2 inch diameter filters.
