does anyone know if wvo is safe to use in a 1989 F350 7.3L, as far as the seal, hoses and the ip goes. or the question that i should ask does the 89 diesels have natural rubber seal and hoses and more important does the ip's and injectors on the 89's use the natural rubber seal and o-ring. any info would be a great help. i plan on running my f350 on wvo soon, right now my taking stock on what all i need to deal with first. don't want to trash the motor.
thanks for the help -BR-

 

I'm pretty sure WVO and rubber are fine together. It's when you start running biodiesel that you need to worry about rubber parts. I don;t know what year Ford stopped using rubber and went to other material
