My hoses and hard lines were a kit for vegetable oil conversions and is not currently available.
You can have similar lines made up at a quality hose shop and there are DIY options available at https://www.discounthydraulichose.co...-fittings.html
The compression fittings are not recommended for high vibration applications. The SS tubing makes this worse. You’d probably be better off using aluminum tubing and nylon ferrules as this is more forgiving. (Ferrules ‘dent’ the tubing for better retention) It’s also way easier to bend.
I went through a a couple of tuners and several revisions to get my hybrid injectors to idle smooth when warm and not smoke like a steam locomotive. Maybe reach out to Brian and let him know what you’re problem is and see if he can help.
The high perdels on #3 and #8 (and sometimes #5) are common and generally have no affect on how the engine runs. I think this happens because of how the CPS and firing order work. In my experience, you need a perdel of >10% to feel a ‘miss’. This will most often be an injector problem. A low compression issue almost always results in pressurizing the crank case resulting in ‘blow by’ that will blow the oil filler cap off upon removal. I don’t put much stock in a static compression test on these engines. More often than not, it’s not done correctly and produces false results.

Never heard of aa tunes. A quick Google search yielded aa design in Washington is this who you are referring to? On another note my brother, Rip Daz, used to do live tuning on audi. He would send out a vag com obd cable and have the customer install nefarious moto tuning software. He would then remotely connect to their laptop and make tuning revisions as they would do test runs. Is there anyone who provides a service like this for powerstrokes?

Yes, Andrew Arthur (AA design) is in WA.
Not quite as convenient as the remote tuning you described, but he will email you tunes and revise them based on your feedback (too much black smoke, touchy throttle, lopey idle, etc).

You have the ability to get really, really bad MPG if you drive aggressively.
In a nutshell, it takes a minimum amount of fuel to get down the road. If you keep your foot out of the throttle, you can attain stock-type MPG even with big injectors.
It’s difficult for me to calculate MPG because I don’t measure how much vegetable oil I put in my truck, but I’ll say I’m using a bit more fuel towing in the mountains and with cruise control on flat ground. (Cruise control is an MPG KILLER!!)

From 8-18mpg depending on driving style.

I have yet to drive a tankful of diesel in my 97 without many full throttle pulls. It really brings out my inner 15 year old.
this thread is super interesting!! I had no idea we could plumb our pumps in-tank. I am currently building a fuel system for my 2001 using a fpr from an obs as the regulator. Any of you that came from the obs world would recognize this as the tightwad mod.
I haven’t finished the filter set-up but it will be similar to my diy kit on my 97, with many improvements from a few more years to learn. Yes, there are barb fittings and regular hose clamps. I know there are more profession ways to do it. That fuel pump is off of a junkyard super duty.
