I ran the fuel low, put some anti algae additive in and ran it till it had about a gallon of fuel left.
I filled the tank with new fuel and added a fuel additive called QMI.
It could be my imagination, but it sounds as if it may be running a little loud and kind of rough.
In reading some of the posts here, I just wonder if the dealer I bot it from may have dropped a can of 2 cycle oil in the tank which would have made it sound quieter.
I ran it low thinking on changing the fuel filter. Is it possible I clogged any of the injectors.
Thanks in advance.
I don't necessarliy think it could 'clog' injectors, but any foreign material that makes it past your fuel filter could damage them. Drain your fuel bowl(I think on the vans, there's a cable to do this) when you change your fuel filter & while it's empty with the fuel filter out, check the condition on the bottom of the fuel bowl. Make sure there's no sludge or rust. Try to get your hands on a scan tool with diesel diag capabilities & check for codes & run a buzz & contrib test. Also: it could just be the typical 7.3 injector 'cackle'. Some additives I've read can make injector cackle louder, but I'm not 100% sure.
