Sump screen fitting part 1

While reinstalling the engine last year, I especially remember one step that made me pronounce bad words: reaching and securing the set screw on the engine oil sump fitting. This fitting is located on the rear bottom of the oil sump. It actually corresponds to the engine oil pickup point from the inverted oil system (magnified below):



Some airplanes may have this fitting easy to access. Mine is a pain.

I currently have the 804-A type fitting:


I suspect the 45 deg swivel feature is for setups where the engine mount restricts access to the fitting. In my case, the nearest engine mount tube is well clear of the fitting, so really, I didn't find any reason to have the 45 deg swivel fitting. More parts, more chances of leak with little or no added value in my case.

I therefore took the decision to switch to the straight 804-S type fitting i.e. from this:



To this:



Currently gathering the parts to make this work. I'm currently in Phoenix, AZ for work so I will take this opportunity to go shopping. Much easier to get parts here than Montreal area...

I like when I can make things simpler!
