For the hydraulic with the red color I will purchase129A00-55730: Yanmar fuel filter element for 3TNV88 Series engines. This is a genuine part covered by a 6-month warranty. Diesel Parts Direct is an Authorized Yanmar Dealer. Buy online or call 888.694.6336 if you have questions about this item.www.dieselpartsdirect.com
from the dealer it might cost more but you can see
