This is the BulletProof Water Pump for the 90mm application.
The Bullet Proof Diesel Billet Water Pump is designed for maximum durability. It features an aluminum impeller in place of the OEM plastic impeller, top of the line bearing assembly, top-grade seal and an all-billet precision machined housing. This stronger impeller resists cracking along the hub helping to prevent impeller failures, overheating engines and expensive repairs. The aluminum impeller is also stiffer and stronger and therefore less likely to flex under heavy loads, leading to less cavitation and less erosion within the front cover. The billet housing is strong and more precise than a typical diesel water pump's cast housing.
Not sure about the diameter of your water pump impeller?
The only way to TRULY know if you have the 90mm or 100mm water pump on your Ford 6.0L is to measure it. However, we can help you make an educated guess.
The 2003 and early 2004 models came stock with a 90mm impeller. The later models upgraded to a 100mm version. Some earlier models might have had their front cover replaced/upgraded over time (to the 100mm version), so it is possible to have an '03 with a 100mm water pump.
Not sure? Either remove your pump and measure it first... or check your VIN code and use this information to determine your model of truck and make an educated guess.
If you have a 2003 you are in the 2003-2004.25 production date, and most likely a 90mm water pump.
If you have a 2005 or newer, you most likely have the 100mm water pump.
If you have a 2004 model you need to check your VIN code to determine your production date.
A sample VIN code is: 1FTRW21P2 4EB10150. In the middle of the VIN code, you see the digits "4EB". The 4 means that it was a 2004 model year. The "E" denotes which production plant built your truck. In this case, E is for Kentucky. Lastly, the "B" is the start of the sequence number (the last 6 digits of the VIN). Some early 2004 models have a "4EA" code. The "A" denotes the early build and most likely is a 2003-2004.25 production date. The "B", "C", "D" or more all denote later model 2004 builds with 2004.25 and newer production dates.
