Onan fuel filter

I decided to service my Onan QD12500 gen set the other day and being the good retired CAT mechanic I am was going to change the fuel filter also. Anybody figured out how to reach that poorly placed devil without taking all the sound box off the gen? Wouldn't be too bad if it was on a slide but it is mounted in a side bay and will have to be removed to do this. If this is the case, the first time will see the original removed and a Racor installed outside. BTW the air filter isn't much better. Just love engineers

Access door underneath...unless there is a floor in your compartment. You can also loosen the 10mm bolts around the top and pull the one side panel off of it as well.

well crawled under the coach today and had a look at the bottom of my gen set, guess what -NO FRIGGING DOOR.
Might just drop by a Cummins/Onan service center on my way south and ask them how to access the filter or maybe better still, ask for the flat rate and let them at it-lol.
