Difference between Hydo and Aqua?
We are trying to understand our system in our new to us coach and are trying to figure out the difference between Aqua and Hydro. Is it just a different name or do they work different?

Do NOT run diesel burner till the fuel leak is fixed as mentioned above.
Fuel leaking from the exhaust hole in the floor can come from several sources.
Leaking from the fuel line connections under the burner is one. If it has run fine till recently, this is probably not the source. Plus there would be no fuel dampness up in the burner unless the fuel banjo bolt in the side of the fuel pump is loose and damp. If that is the source, remove the banjo bolt, replace the copper crush washers and reinstall.
Leaking from the threads of the fuel nozzle is another. Upon removing the burner, the photo disc that surrounds the nozzle would be damp with fuel under the nozzle and the exhaust would be emitting white smoke. If no smoke, this is probably not the source.
A leaking fuel pump shaft seal is a really good source. Fuel would leak inside the case, drip out the fuel line grommet holes down onto the pan and out the exhaust hole.
A new pump retails for $387.30, labor of an hour to maybe two. While the burner is out, clean combustion chamber and replace the nozzle. Reassemble and check for proper operation.
If you can slid over to the Houston area, I will be happy to fix it. But there are several good AH folks in Florida that will do a good job.
