Installed vent and seems to have solved my problem

Ordered mine and finally got it installed. Made a huge difference in the cool air it takes in. Was 92 degrees the other day and the generator ran for hours sitting in the sun and never missed a beat. Thanks for the advice.

THOR #20105
Forrest River Doort vent

If any body is looking for one of those trick generator door vents and shrouds. It is a Forrest River part. Andrew at Mt.Comfort RV outside of Indy has waded through the parts guys and managed to find it. Have one being shipped there now. It seems as it were a bit of a struggle as the part numbers seems to change a lot... it was not even terribly expensive... So if you are looking for one. Contact Andrew there. Truly a nice young man and very helpful.

generator insulation wrap

Has anybody tried to wrap the butter surface of the generator with aluminized heat wrap? We use it on race cars and it REALLY works.. It might drop the internal temps in the air plenum hence keeping the gene cooler and isolating it from the heat generated by the V-10, tire and road....Just wondering.

I installed the vent with the shroud, and it definitely pulled in cooler air. I put larger fuel line over the lines coming from the back to try to cut some heat from hitting them. I replaced my fuel pump again and hoped I had fixed the issue. Last trip on the road in 95*+ temps, the generator would shut down. I ended up buying an aftermarket in line fuel pump, mounted it on the frame rail near the fuel tank, removed the factory pump and installed a fuel pressure regulator there. We took it out of town last weekend, it ran 4+ hours each way in near 100* weather and never missed a beat. Should have done this two years ago.

My 2019 30FE came with this door on the generator compartment. If they have it for my model, they sure should have something comparable for other models.

So your conclusion from this would be that the stock fuel pump is the problem more than the air supply at the generator? Iíd tend to concur inasmuch as Iíve had 4 RVs now with no added air vent and never had a problem. Most recently drove with the generator heavily loaded (AC, crock pot on high and TV) on a 98 degree day (in Iowa of all places) without a problem. SOB but similar compartment open at the bottom only. Maybe there was a batch of weak Onan pumps or something.
