In HEUI systems, high-pressure engine oil actuates the injector and the ECU precisely controls injection timing, giving very accurate fuel delivery under varying engine loads. This injector supports smooth combustion, efficient atomization, and reliable performance over long cycles — making it ideal for large transport or construction machines where consistent power and fuel economy matter.\u003c\/p\u003e\r\\n\u003cp data-start=\"2632\" data-end=\"2662\"\u003e\u003cstrong data-start=\"2632\" data-end=\"2660\"\u003eKey Features \u0026amp; Insights:\u003c\/strong\u003e\u003c\/p\u003e\r\\n\r\\n\u003cul data-start=\"2663\" data-end=\"3247\"\u003e\r\\n \t\u003cli data-start=\"2663\" data-end=\"2764\"\u003e\r\\n\u003cp data-start=\"2665\" data-end=\"2764\"\u003ePart no: \u003cstrong data-start=\"2674\" data-end=\"2686\"\u003e250-1306\u003c\/strong\u003e (also cross-referenced with 392-0212)\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"2765\" data-end=\"2865\"\u003e\r\\n\u003cp data-start=\"2767\" data-end=\"2865\"\u003eCompatible with \u003cstrong data-start=\"2783\" data-end=\"2811\"\u003eCaterpillar 3508 \/ 3512B\u003c\/strong\u003e HEUI engines.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"2866\" data-end=\"2984\"\u003e\r\\n\u003cp data-start=\"2868\" data-end=\"2984\"\u003eHEUI architecture ensures very good control over injection timing \u0026amp; quantity because of oil-actuated system + ECU.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"2985\" data-end=\"3105\"\u003e\r\\n\u003cp data-start=\"2987\" data-end=\"3105\"\u003eHelps restore smooth throttle response, reduce smoke, and recover lost performance in high-displacement Cat engines.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"3106\" data-end=\"3247\"\u003e\r\\n\u003cp data-start=\"3108\" data-end=\"3247\"\u003eMaintenance-critical: as HEUI injectors depend on clean high-pressure oil, any contamination in the oil system can drastically reduce life.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n\u003c\/ul\u003e\r\\n\u003cp data-start=\"3249\" data-end=\"3271\"\u003e\u003cstrong data-start=\"3249\" data-end=\"3269\"\u003eWhen to Replace:\u003c\/strong\u003e\u003c\/p\u003e\r\\n\r\\n\u003cul data-start=\"3272\" data-end=\"3654\"\u003e\r\\n \t\u003cli data-start=\"3272\" data-end=\"3386\"\u003e\r\\n\u003cp data-start=\"3274\" data-end=\"3386\"\u003eReplace when there is \u003cstrong data-start=\"3296\" data-end=\"3313\"\u003epoor starting\u003c\/strong\u003e, \u003cstrong data-start=\"3315\" data-end=\"3331\"\u003eengine knock\u003c\/strong\u003e, \u003cstrong data-start=\"3333\" data-end=\"3352\"\u003eexcessive smoke\u003c\/strong\u003e, or \u003cstrong data-start=\"3357\" data-end=\"3383\"\u003euneven cylinder firing\u003c\/strong\u003e.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"3387\" data-end=\"3516\"\u003e\r\\n\u003cp data-start=\"3389\" data-end=\"3516\"\u003eAlso consider when doing a rebuild — especially if the high-pressure oil system (oil pump, rails) has had issues in the past.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n \t\u003cli data-start=\"3517\" data-end=\"3654\"\u003e\r\\n\u003cp data-start=\"3519\" data-end=\"3654\"\u003eAid maintenance by cleaning or replacing O-rings, checking the oil filter, and verifying high-pressure oil pump health when installing.\u003c\/p\u003e\r\\n\u003c\/li\u003e\r\\n\u003c\/ul\u003e\r\\n\u003cstrong\u003eContact for Orders:\u003c\/strong\u003e\r\\n📞 +91 78885 29020\r\\n📧 paldieselservice.chd@gmail.com\r\\n\r\\nCAT 3508 FUEL INJECTOR FOR HEUI ENGINE\r\\n\r\\n250-1306, 2501306","brand":"Pal Diesel Service","offers":[{"title":"Default Title","offer_id":47639623041198,"sku":null,"price":55084.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/3261\/9438\/files\/ox4kE8oL.jpg?v=1773656136","url":"https:\/\/www.paldieselservice.in\/products\/cat-fuel-injector-for-heui-engine-2501306","provider":"Pal Diesel Service","version":"1.0","type":"link"}
