The engine in F650 and F750 is the Cummins ISB. The ISX is a class 8 truck engine.

I always get them mixed up. Thanks.

DEF, I thought it was diesel exhaust fluid.
I own a early 04 Cummins so who am I to argue, but I will. 2004.5 had a bigger turbo, different injectors, different pistons, 3 injection events instead of two and a few other things I can't remember, but I think the heads were the same.

I wish I still had my 04. Didn't have quite as much power as my 07 5.9 but it got a little better mileage.

DEF I slipped on that one but doesn't matter means the same.
From Pickuptruck.com...
In developing the new “600,” Cummins and Dodge made numerous other improvements or changes to the engine:
• Air inlet redesigned to block hot engine air from entering, reducing the intake charge by 30 to 40 degrees.
• Intake resonator re-engineered for increased airflow
• Larger compressor on Holset turbocharger
• Engine cooling improved with new fan assembly and mounting fan shroud to engine for more efficient airflow through radiator
• Upgraded intercooler
• Upgraded exhaust valves
• Tailpipe increased to 4-inch diameter
• Improved sealing and gasket materials
• Oil-change intervals are now 15,000 miles (vs. 7,500 for competition).
• Holset turbocharger gets bigger compression side
• Switch to electronic control of wastegate
• Upgrades to exhaust manifold
• Revised intake ports in cylinder head
• New piston bowl geometry
• Different spray pattern from injectors

That's probably correct, 03's and early 04's are known for being more likely to drop valve seats. Didn't know about some of those other changes but some I did. I know the power jumped from 305 to 325, mostly due to the bigger turbo.

The 04.5+ engines ran a higher exhaust temp because of the third injection event, but the cylinder temps are similar. It was the method used for meeting emissions. I don't buy the claims that some of the engines got better mileage, I had a 97 12 valve (supposedly one of the best fuel mileage cummins) and it got the same or slightly worse mileage as my 97 5.9. I've tracked very tank on both trucks, and I'm happy with the mileage but the 07 beats the old one by a very slight margin.

Well my lift pump just failed! Looks like I'll need to track down a replacement! Thank you for advice.

Don't have to live there to know some facts....
Here's a map of road salt usage per lane mile annually per state. As you can see, Kentucky uses half as much salt as Tennessee, 6 times less salt than IL, IN, OH. 8 times less that WI, and 23 times less than MI. In fact, KY uses less salt per lane mile than any state east of the Mississippi and north of the Tennessee/North Carolina border with the exception of Delaware. So, yes, Kentucky does not use very much salt on its roads.

Very interesting map. Pa isn't as high as I thought it would be but I still wish we used way less. I would trade messier roads and needing more driving skill for vehicles that didn't rot out so fast from all the salt.

What year truck? Any fueling mods? A fass or air dog system is hard to beat but expensive. The new in tank pumps have proven to be very reliable but I'm not sure of the cost. I think it's "Raptor" that makes a pump only that is reasonable and reliable.

Personally wouldn't get anything from fass again customer service sucked and their "lifetime" warrantee wasn't much better

I have never owned a fass pump, I have buddies that have them but not me. Fass and air dog are the two big names for people who need much more than stock fuel volume.

That will be a county by county variance. Where I live in KY they use TONS of salt and liquid deicer. The more northern counties use a lot. That's a fact!

2004.5. 100% stock. Ordered truck and have driven since 1 mile on odo.
I ordered stock fuel pump from Geno's. Should buy me another 80,000 miles. I'll most likely replace pump as preventive maint. Most cost effective, simplistic solution in my opinion.

The point is, you're arguing that its not a salt problem with Chevys, to a guy that lives in NY, where they use 12X the salt that KY uses, and it affects ALL brands of trucks.

All Brands; are you sure???
