I have Jim K’s conversion. Is there a trick to installing the compressor. I the brackets installed. I had to cut clearance for the fuel line but other than that it went on without to much trouble.

Never mine I took off the valve cover and had no problem putting the compressor in. Hope this is worth it. Once i get it together I will cut some holes in the front of the box and run two tubes up to provide some cooling. One will be run to the seat by the table to see if it will cool a little back there for my wife. Hope that helps cool down the RV a little where she sits.

Art,

I don't quite understand your post, but what I think you're proposing to do
is to add ductwork from the front of the HVAC box, through the firewall to
provide more airflow into the cockpit. That MAY help with cooling -- quite
a few people have done something similar. BUT, the fairly recent
experience of a friend prompts me to issue a caution: Their engine battery
"exploded", causing a sudden burst of flame. The flame should have
followed the firewall up to the base of the windshield and perhaps been
extinguished for lack of oxygen. Or, at worst, burned through to the
outside of the windshield. Unfortunately, a PO had added a plastic duct
firewall above the passenger's feet. That duct was immediately burned
through, allowing the flame to penetrate the firewall, and follow the
cockpit side of it up behind the dashboard, along the inside of the
windshield, over the passenger's head, etc., all the way to the back of the
coach. Essentially everything above the beltline was burned or badly smoke
damaged. Little damage below the beltline.

Without that ductwork through the firewall, the coach might well have still
been totalled -- but with little or no interior damage.

Just something to think about. I know if I were tempted as you are, I'd
use very fire resistant materials (my custom HVAC box is made of 12 gauge
aluminum).

Not sure of the posting, however our Sanden compressor bracket does not
require it to be removed should the valve cover need be removed. Nice
benefit.

FWIW I would make sure the genny works and run the roof ac to keep the
coach cooler in really hot conditions before I would embark on a project as
ambitious as building and running all that ductwork.

Thanks Ken. Something to think about. I need to get some air back where the table is. I guess I’ll see if I can get some metal tubing to run thru the firewall. I have the fire extinguisher set up which will help some but I removed the fender liners to see if that helps with vapor lock problems I been having.

Todd I would if I thought I had a chance to make it work. It’s hard to fix when it run fine at home. I ran it for 4 hours the last time before i left for a trip. It quit within 30 minutes when on the road. I do not know what to do. I changed the coil, I changed the condenser, replaced all the diode. I plan to replace the oil sensor and change the oil. Then insulate the fuel line that runs under the generator.

It runs fine at home, but quits on the road. Could the fuel vents be clogged enough so that the little Onan pump can't get gas, but the engine pump
can overcome the vacuum? I don't remember off the top of my head, but the fuel system has a goofy venting system that when working well saves the
vapor for combustion. What if you try driving with the gas cap off for a while?

Sometimes it is the oil pressure switch that is shutting it off. Need to
install a lower pressure sender.

I wonder if it the fuel tanks are getting hot. I had allot of vapor lock problems and last winter when driving the heater motor was going bad. My wife said it was nice and warm in the back of the RV. So I assumed the tanks might be getting warm.

I changed and put a fuel pump that would mount to the generator. It did not help. I moved the fuel pump off the generator and that did not help.

I never thought about vacuum in the tanks. I not going to leave the cap off the tank, I did not get it tight one time and I had to stop as the smell of gas was to strong. Not going to do that.

I’ve removed the finder liner to allow more air flow around the engine and the headers. I ws going to drop the headers but the center bolt did not want to come out with out some help. I did not feel like fighting them at the time. It was suggested I take the fender liner out. It should help increase the air flow around the headers and under the RV.

Thanks everyone.

Onans that run fine at home then die on the road is usually a kinked fuel hose between the nipple on the drawer floor and the fuel pump. There was a
factory spring to dress the hose but those have rusted away years ago Drawer closed, line kinks and reduces fuel flow just enough to eventually not
keep up.

In one of Onan’s manuals it cautions about using a tee between fuel tanks/ coach engine/ Onan fuel pump inlet and it alludes to a fuel starvation issue as the reason. GMC-upfitted coaches had a separate pickup in the main tank for the Onan per Onan’s commendation but other coaches (like my Coachmen Royale) have the tee. My Royale has been derelict since I bought it so I cannot speak from experience but I tend to put a lot of stock in what the old timers say and if they say a tee’d pickup is a problem then I will defer to their experience and try to avoid such.

Fundamentally there is no reason the Onan cannot run indefinitely while in its enclosure as long as it has 12VDC and uninterrupted fuel.

It is a trivial task to determine if an Onan quit due to a fuel delivery problem: Loosen the carb bowl bolt and see if gas comes out. If it does not then there is a fuel delivery issue. If tuel comes out then the problem lies elsewhere and proceed down that side of the troubleshooting flowchart.

The tee fitting might be the issue or a crimped hose. One way to test for vacuum issues is to drive without the gas cap - just as a test - and if the
Onan quits you can put that gas cap back on happily and tackle the next suspect.

The tee is a typical 'cheap out' by an upfitter. They didn't want to drop the tanks - or at least the rear - to gain access to the genset fuel
connection. If you have an upfitted Transmode, and if there is a tee feeding the Onan, when you drop the tanks for maintenance, replumb the Onan to
the tank fitting.

I forgive them all, save those who hurt the dogs. They must answer to me in hell
 
As I seem to recall, the correct fuel cap will vent a vacuum, but hold back close to 1 psi.

Now, If you have not replaced all the fuel line to the Onan, particularly those sections from the tank to the pump inlet, that could be all your
problem right there. It was for me. Then I replaced the fuel line inside the generator space.
It ran like a watch...
Until I pushed it in and latched it....
It would start to stumble...
Until I released the latches and pulled it out just a little.

That new fuel line was just long enough that if not dressed properly it would pinch off when the machine was home.

I would love to have you believe that I discovered and cure this issue right away and with very little effort......

Matt, the time you spent dicking with the genset to find the pinched line save me the time I would have spent dicking with mine. I think I can
repurpose a piece of screen door spring - if it isn't too strong - to keep the fuel line up when the genset is pushed into the space.

Gentlemen,
One’s intuition would suggest that a big, clunky machine would have big, clunky solutions to problems. That was certainly my initial take on our beloved machine. I learned through hard experience to pay closer attention. This string of posts proves the actual fact that subtlety is more often the route to a solution. As someone who redid all his fuel lines in 2000 and is facing a repeat, this string is a revelation. I never even touched the Onan fuel lines in 2000. My bad. Now I know what to avoid. Let us hope the newbies take the larger lesson and search the forum to read the full discussions and avoid the dead-ends that result in intermittent problems. I REALLY appreciate the back and forth of what people tried and what didn’t completely solve the problem. (Thank you Matt.) Just a comment from a habitual lurker. Thanks again for sharing.

It was about 8 years ago that the hose manufacturers figured out an
inexpensive way to overcome the Ethanol attack on rubber. The trick was to
install a Barrier, nothing more than a thin nylon type hose covered with
rubber.
So, we have coaches that come in and the customer tells us the hoses been
changed, but in the last 7-8 years.
If one does ot know, then they should replace it now along with Fuel pump,
Tank selector valve,Vapor separator and all the vent lines.
