Human Factors
Upon taxi into gate; [guidance system] was active; both pilots cleared ramp area. Approximately 20 ft remaining FO yells for me to stop. I immediately stopped aircraft and FO [advised] fueler was backing up into our safety zone. We were in a B737 MAX with the split winglets and thus the clearance provided below the wingtip was considerably less. After speaking with ramp [personnel] who reviewed the ramp video; I believe the monitoring and quick response of the FO averted possible damage or impact to aircraft. Ramp fueler personnel inattentive to position on ramp. [Not] all ramp personnel may be accustomed to the 737 MAX winglet design and the increased clearance required. Training for this may be beneficial.
