BDLL150S6666 Injector Nozzle Tip 5621713 for Ford 4600 5600 6600 7600 8700 Tractors OE

Description

Genuine Delphi BDLL150S6666 Injector Nozzle Tip for Ford New Holland Tractors

This is a genuine OE Delphi diesel injector nozzle tip, part number BDLL150S6666 / 5621713. Delphi is the direct successor to the original CAV and Lucas diesel fuel injection division, making this an authentic OE-style injector nozzle for classic Ford diesel tractor applications.

These are not low-quality aftermarket copies. Genuine Delphi nozzles are known for precise machining, correct spray geometry, and consistent fuel atomization — essential for reliable starting, smooth idle, clean combustion, and proper engine performance.

The BDLL150S6666 injector nozzle was used in several highly popular Ford agricultural tractor platforms from the mid-to-late 1970s. These nozzles remain in strong demand among diesel injection rebuilders, tractor restoration shops, and Ford tractor owners because original-spec injector components are becoming increasingly difficult to source.

Whether you are rebuilding injectors for a working farm tractor or restoring a vintage Ford diesel, genuine Delphi nozzle tips help maintain the original fuel delivery characteristics that many aftermarket replacements fail to reproduce.

Important Fitment Notice

Please verify your injector nozzle number and engine application before ordering.

The best way to confirm compatibility is to remove one of your existing injector nozzles and compare the part number directly to BDLL150S6666 or one of the listed cross reference numbers.

Some Ford tractor applications used different injector configurations depending on production year and fuel system setup.

If you are unsure about compatibility, contact us before purchase with your engine model and injector numbers. We are happy to help verify fitment.
