If it is gelled up then you need to get a bottle of 911 diesel treat (red bottle). Any size bottle will work. Put in tank and follow directions on the back of the bottle. I don’t know how fast it works because i have never used it but i hear it works great.
Another reason for the $10k is you will probably want to take the ferry back to Wa. Most likely you will have to deadhead out due to scarcity of loads going out. Of all my years of driving, I have not heardof anybody getting a load back out.
I’ve heard while traveling to get to Alaska there are gas stations along the way but few and far between. The best way is to have the extra cans and fuel up at every stop along the way just so you don’t have to use your emergency fuel.
