MrWizard thanks for the suggestion to call supergen. I would like to add to this thread for the sake of posterity, that if you, like me, came here wondering how to, instead of should I do it, once you make up your mind you can call those guys with any questions and they will provide answers and product solutions that are not listed on their site. Also if you are thinking of ordering from amazon, call them first. Very pleasantly surprised!!!
I am actually favoring a vacuum pulse mikuni type pump fed off a vacuum port in the cylinder head. I got that idea from this thread. If you have successfully used this pump to feed a Champion generator I would love to hear your success story. thanks. My two questions are: can you find an existing vacuum port and were you able to draw from your MH fuel tank (which can be quite a distance of fuel line removed from the generator). For about 1/3 GPH flowrate, I'd prefer not to run a pump that is designed to push 18 GPH. I think I'll get better fuel economy, spend less money, and increase reliability if I can make this work.
(has nobody installed a Chinese generator in an open motorhome generator "box?")
I need to upgrade my freshly removed Brand O 4000 and the Champ remote start 3000/4000 looks like the way to go.
? I don't have room for the gastank and I want to take advantage of the motorhome fuel line. Do I simply need a small facet fuel pump 1-4 psi and a 1 psi holley regulator? (I have not seen definite experience on that important aspect)
? My gen "box" is open to the weather, which killed the green monster, but I am developing the weather enclosure (allowing for plenty of air via screen) plus allowing open mesh for intake & cooling exhaust...will I need to add a fan? I don't have a weathertight enclosed box like a TT? The Champion has a fan, like the Emerald has a fan, doesn't it?
The green monster is obscenely loud & we've always hated it - even the little it worked. I would be surprised if the Champ would be louder. I'll pursue the silencing measures proposed in the thread. thanks.
