The boat was hitched, kiteboards, beer and fishing poles all loaded.  My wife and two other couples hit the road and headed south.  Destination: Islamorada, Florida Keys. 

 

In case you don't already know, I drive a 2001 F350 2WD with my Raw Power conversion that I have freely posted on this site (sign in and download it if you are interested).  I have a 90Gallon tank and was planning on bringing an additional 55gallons to complete the 1700 mile trip. However, in the furry of trying to get ready to go, I decided to just go with the 90gallons topped to the brim and I actually pinched off the breather hose so that I wouldn't be leaving a trail of oil for the first 100 miles.  
 
We got underway and the truck switched over to WVO without issue  before we hit the Cooper River Bridge and I got to pull full power over the biggest hill in South Carolina for an initial shake down.  After approximately 5 hours into the trip, location, northern Florida, 80mph, the WVO system was unable to maintain above 65psi and started to kick on the diesel pump.  Slowing down would correct the problem initially but after another hour, the veggie system just couldn't keep up.  Keep in mind, I am pulling a 21ft, Sea Fox that isn't exactly aerodynamic and would say using 80-90% of full power.  Also, I had at least 5000miles on this filter so we pulled over at a rest stop and I Nascar changed the fuel filter.  Hitting the road again, the issue appeared to be addressed but after only a few miles the veggie system was once again unable to keep up at full power.  In frustration, I flipped off the veggie system and drove on.  After a few minutes, I could re-engage the veggie system and it would work for a few minutes then deteriorate.  More frustration.  We pulled over for breakfast and I started to give the system a look over.  Everything appeared to be working and I finally went to have a look in the veggie tank.  Pssst was the sound when I removed the cap..."dumb ass" was the second thought to pass through my mind after the obvious realization that I had left the tank breather pinched off!  I corrected the breather issue and we completed the remainder of the 700 mile trip on veggie without incident other than a "detour" through a bad part of Miami when we somehow lost the Florida turnpike.  Total time 14hours.  Approx Veggie Fuel Econ 10mpg.
We spent 8 days living the life.  In which time I got on to fillup4free.com and found a source of oil about 5 miles from where I was staying.  I happily payed $1/gallon for reasonably clean WVO and topped up my tank to about 80gallons.  (I left the breather alone).  On the return trip I did have to change the filter at about half way (one of the 5gallon cubies looked a little suspect) but smooth sailing at 70-80mph the whole time.
Random observations:  
 
-I did notice a minor power difference between diesel and WVO on the way down when I was flipping between WVO and Diesel.  
 
-I can't imagine a WVO system that runs both the diesel and WVO through the same filter.  Often, when you WANT power, you NEED power.  I would avoid such an arrangement at any cost.
 
-My big bed tank will allow me to suck air into the WVO system due to sloshing when WVO level is low, this is annoying and  I spend a lot of time trying to devise a bolt-on system that would address that.
 
-I don't know that I live south enough yet!
