Ideas to prevent expensive HPFP system repairs

I'm working on a project right now, and it might be ready in a few days for pictures, and a trial run.
It is essentially a mesh "sock" that fits into the fuel filling hole, and it is comprised of copper wires wrapped in nylon thread, formed into a long sock looking thing.
It's a lot of work to make so far, but it should work.
I have a circuit set up on an old electronic breadboard kit, and running the wire sock connected to a capacitance circuit, water seems to be easily detected.
My plan is that this would stay in the filler neck, and when you fuel up, if theres any water, it would beep. That way you know before you fill up on bad fuel.
Once i get further along here, i'll post up some pictures and findings. So far it's looking really promising though, seems to detect the water before it even goes past the wires.
I wonder if it will give different readings for different quality fuel as well? Man, that would be awesome. Kind of like a fuel fill analyser ...

Much like harnessing some Clydesdales to the front tow hooks and going back to old fashioned horsepower. But fortunately this isn't the 7.3L forum and therefore it's not a relevant idea to prevent HPFP repairs.

Hotshot
You and your logic ruining everything.
Can the 6.7 be ran on lower fuel pressure and tuned for the change?

Hummm, I wonder if this could be installed between the LPFP and HPFP? Then if you hear the beep, stop the engine, open the valve on the in line "T" then flush the bad fuel out with the LPFP untill it quits beeping.

My thought process is that if any large amounts of water are prevented from going in the tank, any small amounts from condensation etc would be easily stopped?
What you think?
Plus this wouldn't require taking any fuel system apart ....

Do a tune that run bigger pulse width and less pressure, unless required for high power.
Reduce the average PSI by half or so.
And also, if you put bigger injector tips, you should be able to reduce pressure also.
I think most of the pressure is more for emissions than power, while 30,000 PSI atomises fuel good, 15,000 should also work a bit, lol.

There should be more options for these newer engines in the near future, the price on standalone engine and powertrain controllers is going down fast.
These stand alone units are not hard to program like the stock ones, expect to see forums pop up and lots of tune sharing to start happening.
They also can control ever part of the truck any way you could imagine, there are no limits or ford presets, just whatevers programmed in.
Destroked - THE Cummins Conversion Company : Zeus One unit for the cummins engines.
There are a lot popping up lately, I expect within the next 3 years, these may easily overtake tuners. Most are open source, so you can share tunes, modify tunes, etc.

Right now, depending on your ear to decipher variation in fuel quality.
It could be very possible to alter the circuit a bit to do much more advanced analysis.

I'm thinking most of us want better fuel, but this device i'm talking about, along with the other stuff in this thread, is mostly aimed at a "what if" scenario.
Like you could go years putting good fuel in, then what if you fill up one day and get a gallon of water from your usual station....
Do you trust the stock system to alarm you and clean out the water?
Maybe you think that rare case is not worth doing anything about.
I think that because of the expensive fuel system on these newer trucks, extra steps could be taken to insure this doesnt happen.
