Mr.C and I have the system.

There are two settings each switch controlled. There are fixed
orifices(changeable) on each of two channels. The green channel is on all
time (they suggest , I don't do this) It is a low level just to "eat" off
the carbon (this is what they say) when you are running around town. The
Yellow channel has a larger orifice that comes on when the vac gets below
about 5-7 pounds of vac. So when you have your foot in it on ramps or in
mountains it kicks in to raise the octane of the new gas and stop the ping.

I cannot say if it works. Part of the reason I want a knock indicator so I
can test it.

I was looking for a cheaper way to get the sensor. So thought would make
my own .. we will see

I think the US does not mix butane , when I went to Mexico they said was
mixed there but not in US ..... so do not know for sure.

Prob a small point since do not know if system works any way.

Gene and I use a propane injection to bring a small quantity of propane
directly into the carb or in my case, the system has two switches. The first
one runs all the time and puts in a set amount. This helps keep the engine
clear of carbon as propane reduces carbon. The second one is on a vacuum
sensor and comes in when the coach vacuum gets to about 7". Thus when you up
a hill it will automatically cut in the second injection and put more propane
in. That's what gene and I run.

Do you use the propane as an additive to the gasoline or do you use strictly
propane. I wish you would have shown this off at the rally. Things like this
are of value and interest. I do know that if you use propane it must be like
a tank for our other propane uses. What is the weight differences between the
propane and the gasoline? I see there are lots of commercials going to natural
gas including a lot of the government on Vandenberg AFB. What kind of mileage do
you get with your set up. Hanna and I got 10. even pulling and using roof air
coming to NM as we did not have dash air. Emry fixed that for us and we have not
calculated the total trip yet. She goes into the hospital tomorrow. See ya

Ok Al or Gene. Who knows enough to do this set up for you or is a simple thing I
could do? Where do you store the propane or do you run the line clear from the end
of the GMC's household propane, e.g. refrigerator and heater?. Chuck

OK here goes. There is a special fitting on the tank that is a safety switch. In
the event that gas runs faster than normal (ie if there is a break or breach in any
of the propane lines) the flow of propane is stopped. A special hose runs from the
propane tank to the front where there are two solenoids installed. Both are on
switches. One allows a small quantity of propane to go into the carb (EFI) as a
vacuum sucks it in. You still use gas but the propane is to ensure a clean burn and
lower carbon buildups. The second solenoid is connected to a switch to turn it on,
plus a vacuum setting that senses when the vacuum gets down to a set level. Mine is
set around 7" and if the vacuum drops down and if the switch is on then a higher
concentration of propane is brought into the vacuum of the carb (EFI). This amount
is set by the orifice that you specify when you install the system. The larger the
orifice, the more propane you inject. Thus it helps when you are climbing hills or
needing more from the engine. Otherwise the second solenoid does not come on. The
first one can be left on and it lets in just a small amount.

hope that helps.

Yep they have a version for the Onan they talk about it a little on the
brochure on my web page. However it requires drilling into the intake
manifold. I have not installed mine yet because I am looking for an
insert between the air cleaner and the carb. There are some but seem
expensive.

Before we run too far down this path, we should consider the other sides of
this.

1 I do not know if it works. It would be good to have some solid data,
but we do not at this time. Most of the claims are hard to prove.

2 The propane is on all the time, there are special safety valves, but I
know some of you do not leave your propane on all the time. I do for the
refer.

3 There is some complexity, a propane run to the front of the coach,
valves located in the engine compartment,and switches to the driver area.

I believe the vendor will install this system and they are located in
Sacramento, CA. Osborn in NM also installs these systems.

Yes, gene and I bought the one for the onan, but have not had time or
sufficient interest in drilling out the manifold and putting in the injector.
Gene just send some email that shows a web page that might be a simpler
solution for the injection to the onan. They even allow the onan to run
directly on propane.
