Cummins 3914090 Fuel Supply Tube - New

Genuine Cummins 3914090 fuel supply tube — a pre-formed rigid steel fuel line with a threaded swivel-nut compression end and a shouldered/ball-seat tube end with integral flag tab.

Application: Cummins diesel fuel system. The specific engine family and fuel system configuration are not verified — buyer must confirm against engine serial number and CPL. Do not assume interchangeability with visually similar fuel or injector lines; length, bend geometry, and end fittings are configuration-specific.

Condition: New / NOS, unused, supplied in the original Cummins labeled poly bag as pictured. Packaging shows storage creasing and light dirt. No testing claimed or implied.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
