Seller links checked . Prices and availability can change.
Confirm engine, production date and VIN before ordering. Diagnose reservoir level/aeration, suction hose, pressure hose crimps, pump shaft/seals, cooler loop and rack boots before condemning the rack. Never substitute an HR pump or hose family for a DE/RevUp application from appearance alone.

The checked catalogs support the AM810-to-AM81A, CF40A-to-CF40B, AM600-to-AM605 and EV00A-to-EV00B chains. They are separate production/engine families, not one universal chain.
Fitment
Confirm engine, production date and VIN before ordering. Diagnose reservoir level/aeration, suction hose, pressure hose crimps, pump shaft/seals, cooler loop and rack boots before condemning the rack. Never substitute an HR pump or hose family for a DE/RevUp application from appearance alone.
Aftermarket options
New OEM pumps remain cataloged for some applications. Several complete pressure-hose sets are discontinued, so a verified used assembly, specialist-rebuilt line or application-specific aftermarket hose may be necessary. Used hoses require careful crimp, corrosion and contamination inspection.
Before you buy
Hose and pump families split by engine and production date. Two complete OEM hose families were explicitly discontinued, so seller scarcity is real. Cart or ship-time language is not guaranteed fulfillment; bleed with the specified fluid and do not replace the rack without isolating the leak/noise source.
