That is the same part that NAPA sells and it does NOT require a spring. I have used those hoses without any problems. Gates may sell the same basic hose with a spring (different part #) for some lower hose applications. NAPA also sells a flex hose that can be substituted and may be trying to avoid confusion between the two hoses. Hope the helps.
