This is the Alliant Power D27336, a new pencil fuel injector, not a rebuild. It is Alliant Power’s own version of the Stanadyne 27336 and replaces John Deere RE37503. It is the injector for turbocharged John Deere 300 Series engines such as the 3179T and 6359T, for the 4276D, and for the 6414D and 6414T. Tractors that use it include the 2140, 2640, 2750, 2755, 2850, 3255 and 4050.

A pencil injector that is worn or stuck shows up as a miss, white or black smoke, a fuel knock, hard starting or fuel wash on one cylinder. Pencil injectors for these engines look almost the same from one number to the next, but the nozzle and the opening pressure differ, so match the number stamped on the body of your old injector before you order. One injector per cylinder.
