Diesel Fuel in the Valley

[pattypape]

Ken,

Thanks for the response,

There is some information about low sulfer fuel causing problems on
the Cat RV Forum. I am still trying to collect information on
changing the throttle rod seal, Cat said this is a common leak.
I am trying to decide if this is a repair that I can complete.

So, it might be wise for owners of the older 3208's, to have a
solution ready, if or when their throttle rod seal begins to leak.
