That article neglects to mention that a 1/16" diameter restrictor needs to be added
It was a 1960 261 - which can accommodate a full flow oil filtration system
The stainless braided hoses are not mentioned, the stainless adapters with the stainless restrictor . . .
They did mention hoses: "We managed to use braided steel hose from another project that was laying around, and we repurposed them for this project. You need to be aware that raw braided stainless hose stock and fittings will need to be sourced to complete this project. Truly a cheap conversion that adds a lot of modern efficiency to an old warrior." (they also showed/used "available" adapters)
"stainless restrictor"?
They did not mention the oil pressure sender location.
