hi folks

does any one know if there is anything special re the hoses on these pumps. i'm hearing rumours of a restiction built into one of the hoses to keep pump noise down. my 56 truck shop manual refers to "the specified hose" but does not explain any further. as i'm using a Toyoda steering box i'll have to get hoses made so need to know what if any restriction to use.

any help greatly appreciated
