Product Details

The Industrial Injection 0 986 437 303SHO is a remanufactured and modified CP3 high-pressure fuel injection pump engineered specifically for 2001-2004 Chevrolet/GMC Duramax LB7 diesel engines. This performance-upgraded pump delivers 42% more fuel volume than the stock CP3, providing the additional fuel supply necessary to support moderate power increases and performance tuning.

Key Features:

  • 42% increase in fuel flow over stock CP3 pump capacity
  • Remanufactured OEM Bosch CP3 core with precision modifications
  • Direct bolt-in replacement for LB7 Duramax applications (2001-2004)
  • Supports up to approximately 550-600 horsepower depending on tuning and supporting modifications
  • Factory-style mounting and connections for straightforward installation
  • Professional remanufacturing process ensures reliability and performance

This modified CP3 is an essential upgrade for LB7 Duramax owners running aftermarket tuning, larger injectors, or performance modifications that exceed the stock fuel system's capabilities. The 42% increase provides substantial headroom for street performance and towing applications without the complexity of dual pump systems. A refundable core charge applies and must be returned using the provided core return instructions.

good service poor tech support

Autoplicity had the lowest price I found on the product I wanted. Also, the item was shipped very quickly. I received 2 days after I purchased it. Great service!

Found exactly what I was looking for!

Easy and quick check out

I am really impressed. I placed my first order on Monday evening about 7:30 pm and it was delivered to my front door today (Wednesday morning), less than two days later. And that was with ground shipping! On top of that Autoplicity had one of the best prices. I WILL be ordering again from them.

Great

Quick and easy!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Cheapest around, excellent shipping, easy to use website! ill be back!!!

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!

After placing my order, my item was shipped out the next business day as promised. Great service and great products, what more could you ask for!!
