[Fot] Question on Accusump Install with External Oil Lines On a Spitfire

[Bill Babcock]

I agree, I use a single line. I think people are trying to get around  
making the gallery plug hole bigger. Nerve-wracking to drill on  
something like that, but worth doing as long as you can catch all the  
chips and clean the block after. I have also taken that opportunity to  
enlarge the bearing feed holes.
