So ive had my Air Dog 150gph for a year and a half and the other day the pump motor started a high pitch whineing like the bearings are going inside... anyone know of a rebuild kit for the motor or just motor replacements or have had this problem? truck still runs but i think its a ticking time bomb

 

Does this high pitch whine occur prior to start up when your fuel pressure comes up?

 

no only when running, new pump on the way though, life time warrenty

 

did the new pump change the noise
