Put Your CAT 315, 315B or D5G Back to Full Digging Power

Uneven power delivery, black smoke, or hard starts on your Caterpillar equipment? Worn injectors across multiple cylinders cause exactly that. This complete 6-piece fuel injector set (Part# 128-3293 / 1283293) replaces every injector in your CAT 3046 engine simultaneously — restoring balanced, precise fuel atomization across all six cylinders and giving your machine the clean, responsive combustion it was built for.

One complete job. No mismatched injectors. No cylinder-to-cylinder variation.
