It was 4 inches in diameter, 8 inches long with IIRC a number 8 hose feeding it (could have been 10 but I doubt that because the hole in the fitting is the flow limit at that point). It was just bigger than an oil filter.
And the five number 4 hoses came out of the bottom of the can. The cam was .125 wall mild steel. I did the first one in .125 aluminum and it split the can at about 90 psi. I could have used a thicker wall aluminum but I wasn’t about to make 3 if that bugger failed. I actually though about starting with a 4 inch diameter round bar of aluminum and machining it to about .250 wall to eliminate the seam, but I talked myself off that ledge pretty quickly and just made it from MS.
