Fuel economy

[Al]

Ryan,
With an '86, you are certain to have to change out all fuel lines
in her to make them compatible with your biodiesel. The biodiesel
will eat out the fuel lines from within. They will not fail
overnight and you will start to see them leak. But rest assured, it
will have to be done. Bob Loomis and dropped a 150 gallon tank in
mine and I would hate to have to do it will 300 gallons. Word of
advice, when you do it, go buy all-thread and use them to lower the
tank with fuel in it. Chances are you will have all the spray foam
on the tank. When we did mine, even with some fuel in it, the tank
did not budge. We had to top her off and use the weight to lower and
then drain out the fuel. Took us better part of a week but now we
could probably do one in a day.
