I know what the BMK-13 is, I HAD it on my car.

It looks like the BMK23 has replaced the BMK13. The hose dia is 1/2" I.D. I always try to keep the lines as short as possible. Years ago I replaced the hose on the Buick with steel braided (Earls -10) I think. (CRS).

The hose diameter on the BMK-23 is 1/4" and does not mount the full-flow filter.

Your looking at the BMK-21. The BMK-23 has a full flow & by-pass filters and .5 1/2" I.D. hose.

Actually, I was looking at the BMK-22. 1/2" is still too small to feed that setup.

-10 or 5/8" is what I'm using on my filter relocation kit. I also wouldn't go any smaller in diameter.
