Yesterday I decided to tackle replacing the air filter. It took a little over an hour but next time I’m confident it will take about 30 mins, maybe less. I found a small access panel in power cord compartment. I removed four screws and the panel and found the two latches that hold down the filter. I released the latches. Then laid down under the coach and easily loosened the clamps holding the elbow to the filter. Just in front of the power cord door there is a small fake door with vents, there are two self tapping screws holding it closed. Remove the screws and lift the door. The door does not have a lifting shock to hold it open. Behind the door is the air box I had one screw holding it on. I removed the screw and dropped the plastic air box. The hose was not connected to the air filter it had come loose and lost the clamp. The air filter simply slides to the rear of the coach and drops down past the muffler. After removing the air filter there is an end cap on the filter held on by three screws. Remove the screws, clean it and slip the intake hose to it and clamp down. Next to make the job easier feed the hose from the space where the filter sits and run the other end of the hose that connects to the intake box through the frame it’s pretty self explanatory when you see the hose. Next attach the elbow to the other end of the filter I left the clamps a little loose. Slide the air filter back up past the muffler and into its original spot. I didn’t tighten any clamps or reconnect the elbow to the engine at this stage. Instead I pulled the end cap with the intake hose attached and connected it to the air filter with three self tapping screws. After attaching the hose to the filter I finished sliding the filter into place and attached the elbow from the filter to the engine and then lastly I tightened all the clamps. Lastly I reattached the hose to the plastic air box, put the air box back in its location and screwed it in place. I’ve attached a few pics just to give an idea of what you’re working with. I actually found the remains of a rather large bird in my air filter! Tools are simple, a 3/8 socket 10mm deep socket a 1/4 inch socket screw driver and a box cutter.

Good morning. I too have changed the air filter on my 2007 Tuscany 4055. Took me little more than an hour and next time should go much quicker. Only other thing I might add is Freightliner or Damon could have made the air filter more accessible. My last coach was a 2001 HR Ambassador, took all of 5 minutes to change the filter. Have you changed the fuel filter mounted on the engine? Bit of a trick. All in all, love my Tuscany.

I have the bedroom floor panel off and can see the fuel filter. I was wondering how that was gonna come off. And if I have to prefill the filter before installing the new filter

Good morning again. Concerning the engine mounted fuel filter. I placed a large catch pan on the driveway under the engine to catch the old filter and fuel. You will need a filter wrench to remove existing filter, kind of a trick navigating the wrench onto the filter. You'll have to position the new filter beneath the filter housing. Do not pre-prime the filter before trying to position the filter, avoids making a mess in your coach. Then, using a plastic 1 gallon gas can, I inserted about 18" of 3/8" fuel line hose into the pour spout and taped it securely so it wouldn't leak. With less than 1/2 gallon of diesel in the can, I positioned the 3/8" hose over the fuel filter and slowly filled the filter. After filling, I could then raise the filter up to the housing and spin it into place. Hardly spilled a drop. Hope this helps.
