Hi C lectric. Thanks for the feedback. I found a technical specification on the Vetus web site for a pump similar to mine, but they did not include hydraulic fluid info, though I see they market their own transmission fluid. I sent them email, asking which fluid I should buy for my steering system.
What's the difference between something like West Marine Hydraulic steering fluid for $23 a quart, and universal hydraulic fluid for $20 a gallon? It doesn't look to me like my 1987 vintage steering system is anything close to being a state of the art hydraulic steering masterpiece.
