Lower screen fitting

[Chuck]

I have a parallel valve IO-540 (with Barrett cold air sump) and stock Steen engine mount. My previous Skybolt had the Aviation 45 deg fitting on the lower screen for the inverted oil. I am purchasing bits for my project and today’s question is: Does anyone happen to know if the 45 deg fitting is required or can I use a straight fitting from Raven?

Thanks

Chuck
