Before ordering engine hoses, please make sure of the following:

The hoses listed on this page are for engines that have a 1.75″ raw water circuit. If you have an older B series engine, you need to make sure that your hoses are 1.75″ and not 1.5″. Engines that have an aftercooler with a 90 degree water outlet typically have 1.5″ diameter hoses. If you’re not sure, call us with your engine info (ESN, CPL, etc.) and we’ll help you figure it out.
