Marine Diesel Rubber Hump Hose Exhaust / Air Coupler - Used

Application: Heavy-duty molded rubber hump hose / coupler suitable for marine wet exhaust or diesel charge-air / air-intake connections (approx. 5 in ID, USA-made, reinforced multi-ply construction with center convolution for misalignment and vibration). Visually consistent with Cummins-style hump hoses (e.g., P/N 3030768) but must be verified. Condition: Used take-off in good serviceable condition — supple rubber, no visible cracks or heat damage, clean round bore, light surface dirt only. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
