THOR #3916
Pre ULSF & Bio-Diesel Aqua-Hot & Oasis units

Just a heads up on coaches that were built with the Aqua-Hot & Oasis units prior to the introduction of ULSF Bio-Fuel mixtures..
The earlier fuel lines are not comparable with this newer fuel blend.
Found that my Aqua-Hot was failing to fire off intermittently... most times when during heavy & constant usage (cold/below freezing weather..was blaming the burner/fuel pump/igniter coil..
Nope... none of the above
fuel lines from the tank to the filter to the burner had deteriorated far enough that it was "sucking air" thru the walls of the hoses...We found a steady stream of air tiny bubbles in the see-thru glass bowl @ the fuel filter.......replaced all the lines and...... WALLAH!
We HAS Heat!

Will be replacing the fuel & return lines for the generator and big engine in the very near future.
