We have a couple maintenance issues with our recently purchased Excursion 33D.

First, the Cummins ISB 300 users manual says that water should be drained from the fuel filter daily. Does anyone know where that filter is located, how to get to it, and how to drain it?

Second, does anyone have suggestions on how to get to the coach batteries to check water levels and add water if needed? Access to three appears difficult and to the fourth, impossible.

Thanks for any Ideas.

We haven't had a problem of kinking of the sink hose, as far as we know, but we've never had very high water flow to any location.

Regarding the batteries, I suspect they will have to be removed to check water level. What a poorly designed use of space for the batteries. Also, you should pay special attention to the one, fairly accessable battery in front of the DEF tank. It's location is open to the road, just behind the rear wheels where it will gets very dirty with road debris which could have a bad effect on that battery's performance and shorten its life. It should be cleaned frequently. Don't know why this compartment isn't enclosed.

My other question was about the FUEL filter, not the water filter.

I went to water filter, and only now noticed you are talking about fuel filter...I didn't see the drain requirement, but will look for the filter on my rig and let you know what I find....I think it is in the hatch from the back, but don't know now....my duramax had a sensor wire from the bottom of the filter that let you know when water buildup was too much....in 35k miles over 6 years it never went on warning....I changed the fuel filter every 10k so 4 times over that time period... 

I took up the hatch under the back bed, and looked in all the basements....never saw one....I think they are normally attached to the engine block....let us know when you find it...we are going to Decatur in Sept, so if we don't know by then, I will ask...
