Overview – FUEL INJECTOR C4991297
The Cummins FUEL INJECTOR C4991297 is specified for Cummins fuel-injection positions and is supplied to the original dimensional and material standard.
Parts Characteristics
A fuel injector that meters the fuel so the burn stays even in the fuel injection, so the injector bore stays seated and sprayed. It carries the service life the fuel injection depends on, so a true, correctly specified unit keeps the carbon and clog from the cylinder misfires and the power drops.
Applicable Models & Applications
Used at Cummins General Parts positions specifying this FUEL INJECTOR. Match the form, fit and contents against your old unit – General Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A fuel injector that has begun to fail lets the injector bore drift, and the drift is what causes the carbon and clog.
Confirm the fuel injector seats and the fixings hold on fit. A unit canted in its bolts lets the injector bore move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A fuel injector reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct fuel injector for your general parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
Price Reference (USD)
The FUEL INJECTOR C4991297 generally falls in the USD 15-130 bracket, with expedited freight quoted separately.
Value & Service
