You might want to see what the folks on the Org have to add to this. These are probably the two most active 6.0L forums.
I do know of one moderator that thinks very poorly of these pumps, but I just didn't think it was a huge issue. Thanks for starting this thread.
I do wonder if being tuned (or heavily tuned) has an impact on failure rate. I have been on the SRL+ for over 100k miles, so it hasn't been an issue for me, but maybe it could have an impact.

For me, being on the .org is like going to a Proctologist.
I would expect going to a higher pressure fuel pressure would be more of strain to the HFCM then any tuning. The regulator being a bypass circuit will always have a throughput of the relative same volume, summing the fuel used plus fuel returned from my view. Increasing the pressure, even the 55 to 65psi boost could have if it's not designed for it. But it's supposed to handle 100psi, so who knows.......

I wouldn't count mine into this equation as I think the dealer was trying to soak me for mine. I had just replaced 2 injectors and they did the updates on that side including the Blue Spring update. I noticed a high pitch whine once I got my truck back from the shop. I brought it back to the mechanic and he listened to it and "ya your fuel pump is bad". Truck was at a 100K. After hearing how much I said screw that I am doing it myself and I did. Ironically, low and behold the new pump is making the same noise. So at this point I swapped out a pump not needed but on the bright side I have a good spare and I am not using that dealership again for repairs.

156,000 on mine. I found the HFCM drain plug corroded and the stem is missing. I know when I opened it up a gush of fuel came out (I think because the engine filter was open) so hopefully all debris from it got washed out too. Where did the stem go?

Does it need to be removed or is it ok? Will a new plug be able to be installed without a problem if it is in there?

I guess I am confused then, it is the original plug that is corroded (with the HEX head), did it have a shaft or was it just a plug?
