KA24DE: S13 oil pump vs. S14 oil pump

[Decker240]

What's the difference? I see that they're different part numbers so I assume that they're physically different ... but can anyone confirm it?

Are they interchangeable?

Thanks,

I've used either one on either block. The upper cover and valve cover are what's really different. The oil pickup also has an additional leg to brace it on S13s.
