Hey there folks,

Curious as to who has the "go to" HPOP for an early build 03 F550 (12/21/02 build). Long story short the truck came to me in pieces and against my better judgement I agreed to fix the truck. I was going to put a new HPOP in the truck but I decided that I didn't want to "spend" the customers money if it wasn't needed, guess that bit me in the hiney.

Thanks,

Lots of folks are saying good things about the HPOP from CNCFab, but it appears to be out of stock.

The Adrenaline pump is nice, but more $$'s.

I'm not sure I would go with any other choice.

 

I put a Motorcraft in mine back in the spring. It has a little over 6000 miles now and is doing fine.

 

I just asked this question as well. I have Warren diesel 155cc injectors in mine so I called them and asked, they said the stock pump would be fine and I couldn't justify 1K bucks for adrenaline hpop! So went with a stock pump.

 

IMO this part should last 200K+ miles. Lots of threads on early failures of the stock pump - a lot earlier than 100K miles.

If the wait for the CNCFab pump isn't too long, you probably wouldn't be paying much more than what the stock pump cost. IIRC it was around $800. It has been upgraded to eliminate a housing design flaw (and so has the expensive Adrenaline pump).

If I were looking to buy a used 03 6.0L, and there were two identical trucks with only the HPOP being different, I would easily pay $500 more for one that had an Adrenaline pump. JMHO.

 

My original lasted 212k miles and was one of the reasons I went oem. There was a warning in the the instructions to prime the pump per instructions, apparently pumps were being returned as faulty when the installer didn't follow instructions.

My luck with the $1000 pump would be it fail and the company go out of business, then I am stuck buying a oem without a core.

 

 

Good to know (still don't think I would trust them - too many failed early from the factory which isn't an installation error).

Also Ford states to clean out the HPOP sump (under the oil cooler) and the feed line to the HPOP after an HPOP failure. This could cause some of the issues as well.

Still - (correction) only one report that I know of on Adrenaline failure, so I doubt installation error was the total picture.

 

No, it went long ago. It was a separate full sheet of paper, highlighted in red and yellow. Definitely gave me the impression that installation error was a major cause of warranty returns.

 

When mine failed, it would only make 1500 psi @ 84% ipr, it ran fine just low on power, I was 5 miles from home. Everything tested fine but when I pulled the pump it had a tight spot when turning by hand. The replacement looked brand new from the outside, not even a scratch on the housing. I would hope by now they have solved any issues with the pump.

I'm sure the Adrenaline is a great pump, but so is a 2019 6.7, I don't have a need for either one.

 

Well said!

 

 

I did stand pipes, j tube and the 2 flex hoses to the logs when I did mine. I replaced all the injectors @ 175k. I hope I am done for a while.

 

I justify the extra cost in the fact my time is worth something.
I know the OEM pumps are not ALL bad, or the dealers would not be using them. That said, they are a little more inclined to use a OEM rebuild unless the customer specifies something else

 

Thanks fellas,

This trucks been a basket case since the beginning. I suspect that the root cause of the original issue was the HPOP failing, it wont even build 15psi, the entire oil system is clean, standpipes have been replaced. I just want this nightmare to be over. Ill call and see what the lead time is on the CNC unit, and check with the customer to see if they want to wait, pop for the adrenaline, or go oem...either way it sucks when you've had the cab off, engine down to the block and you go to fire it up and the thing wont build oil pressure.

I guess that's what I get for saying Ill work on your truck that's 1/2 disassembled! Shame on Me!
