I 've been running WVO for 15k miles now. Truck is on diesel.
Coon, truck ran all night tonight. I took it out on the town and it went everywhere. It had a big power problem but it ran and always started after I put in a new CPS. I would get on the highway and I would loose power and it would have to drop to 3rd to get up to speed.
I am going to clean the fuel bowl tomorrow. You still think I should pull the IPR?

Time to get a fuel pressure gauge installed that you can read running down the road. Whether you repalce the schrader valve or just use the pipe thread that is there for the gauge you need to know what fuel pressure is.

Flea, did you replace your schrader valve to check real fuel pressure? I'm not saying that is your problem but without really knowing what the fuel pressure is that leaves a big gap in the troubleshooting arena.

So called the dealer and they said they ran the truck on the scantool and the IPR was okay.
The CPS show up as being bad. Of, course I had to change it again for it to run.
I am trying to find a fuel pressure gauge locally.

Autometer makes one. You have to get the adapter that threads into the schrader valve location.

Your WVO system has electric pump.
You are using the oem filter setup and fuel pump for #2 fuel?
Is your WVO low pressure? I would like to see how the fuel system
is plumbed. Is the WVO being pushed into the oem pump?
In OBS WVO systems you really have to toss the mech pump.
It might have just caught up with you after 15K
This needs to be looked into.
"Really hard to open fuel filter. When I do air blasts out and feels like it is building lots of pressure. Could this be a problem and lead to mine?"

Do you think a CC test will help show below?
It could show a damaged nozzle or gasket allowing combustion past the o-ring into the fuel system.
Just a wag.

if there was a blown copper ring then the oil o-ring would be out too. there should be fuel in the oil if that was the problem. also an easier way to check is have the truck running and open the fuel drain and see how the fuel looks coming out of it.
also, most of the time when combustion gets into the fuel system you will have enough to blow the fuel clean out of the lines and the truck will have a hard time priming itself. his is too random for a bad injector seal in my opinion.

indeed, thats really neat to see (as long as its not your own truck) lol
i have seen them blown out so bad that the combustion gases are blowing up around the base of the injector where it mounts on the head.

Okay. Tried to make a fuel pressure pump.
Well it made my day worse. Truck ran better on WVO, while on the way to get fuel pressure pump.
Guy at Machine shop gave me wrong threaded piece to try and plumb into the hole where the schrader valve was at.
I cracked the Fuel header or the thing that is attached to the fuel bowl.
So got a new fuel filter housing from ford and all $471 later I will be putting on it in tomorrow.
So do I need any special tools? Is there any strategy?
I also got the IPR o-rings so I can check and replace if need be.
