Yes, it was made for the Cummins ISC 8.3, and 5 more listed under compatible equipment. Check the old fuel injector is marked 0432191352 or one of the cross references, because makers change parts between serial ranges.
On the Cummins ISC 8.3, often 5,000 to 10,000 hours, but much less on poor or wet fuel. Injectors are usually changed when they fail a test, not by hours.
Black or white smoke, a misfire or knock on one cylinder, hard starting, higher fuel use, or a high return leak or balance rate on test.
Run a return leak test or read the injector balance rates with a diagnostic tool. On older mechanical engines, cracking each pipe in turn at idle shows which cylinder changes least.
Always. Fit a new copper washer and O-rings under every injector you remove. A reused washer leaks combustion gas and carbon packs the bore.
No. It is an aftermarket fuel injector made to replace the Bosch 0432191352. It is not made by the original manufacturer; the number only shows what it replaces.
