So this past trip, I was having the generator shutdown uncommanded due to what I believe is vapor lock. I took it into Onan and they couldn't figure anything out. Tech said they typically install an aux fuel pump inline with the factory one, outside of the Onan compartment. He said that would resolve the vapor lock issue. But I also noticed that the 2017 models now come with a generator vent on the door panel. So I emailed FR asking how I'd go about purchasing this vent/shroud since I don't have an FR dealer near me so I can resolve the vapor lock issue. They offered to send the vent/shroud to me for free and apologize for the inconvenience. I was pleasantly surprised for sure. I just didn't want a generic cover on the side of our 2015 30DS. Anyways, here are some pic of the installs if it helps anyone.

Tools I used on the vent install was an angle grinder with a cutoff wheel, hole saw with drill, and a flat/half radius file. I need to order some lap sealant and butyl tape along with getting some screws from Lowes. But this should resolve any vapor lock concerns for sure. Between the shroud/Gen, I have about 1/2-3/4" gap. Definitely feel the cool intake air rushing into the generator. I had to trim the outer ring as well as the depth of the shroud.

Vent Cover PN: 70A08495A
Vent Shroud PN: 70A08493A

For the fuel pump, I replaced the old stock one with a new one in case it was getting weak from being so hot and moved the fuel filter aft of the aux pump. Solder into the same power supply for both pumps. Tech at Onan said the PCB can handle the additional amps.

Aux Fuel Pump: Airtex E11005 ($49)
Wix Filter (33001): $4
Replacement OEM Pump: Airtex E11006 ($33)
Brass barb fitting, 1/4"ID x 1/8" NPT ($2)

Hope this info helps someone. :trink39:

Did something similar on my old Mirada last year.

Generator Compartment vents | 2001 Coachmen Mirada 300QB

These vents are from a Skidoo watercraft..

Timing is everything. I had sent an email about a week ago asking the same thing, how to get the vent. I also was pleasantly surprised when the reply came back that one was on the way to me. I hope to get it this week. Thanks for the pics. Now I know how to install it.

I too am impressed with Forest River Service. Sent a Email to them about the door vent for generator and Chris of warranty from Forest River is sending a baffle and vent at no cost to me. Thanks and a hat tip to KansasFR3 for bringing this to the forums attention. Including the install process. :trink39:

Added the aux fuel pump and we are off again on the hot highway. Thanks for the post and I will let you know how it goes. Not sure how to order the vent /shroud. But will figure that out when we get home. Nothing like working on things on the road :)

Great job on the vent and the same for the others who have modified there compartment doors. Great thing about this forum is your experiences that you have shared will without a doubt save others much frustration and money.
