gas generator tank on diesel bus
« on: May 26, 2013, 10:29:54 AM »
So the bus is diesel powered, but my generator is gas from an old s&s RV.  What kind of tanks are you using and where do you put them?  What kind of capacity should I plan on for running the A/C on the road?  Genny is an Onan 6.5.

eddieboy,

When we converted our 4106 I installed the generator and gas tank both in the former A/C condenser compartment. I made the 20 gal. gas tank to fit the angle of the front of the compartment and there was just enough room for the generator. Twenty gallons of gas was good for about 40 hours of generator run time at half load as I remember it. The way we used the bus, that was enough. Your use will dictate how big a tank you need.

Good luck, Sam

I had to do the same thing and use a 6 gal plastic boat tank securely tied down with a ratcheting strap. Works fine until I reinstall the diesel gen.

Average load on the NH 6.5 Will require about .75 gph.

We also used one of the former A/C ventilator compartments. The tank we built for it holds about 50 gallons. Our goal was 48 hours without refilling. Check out this page of our build to see some pictures of it.

Dunno bout the 06, but my 04 has an aux fuel tank just aft the front axle for the original gasoline-engine-driven air conditioning compressor.

Ted -

That extra fuel tank is exclusive to the 4104. 

The 4106s and later all used an engine-driven HVAC system.

FWIW & HTH. . .

Thanks, RJ.
 I wasn't sure about the 06.

We have a 35 gallon tank in one of the bays.  It is vented through the bottom.  I have not noticed any fumes in the bay.  This is the way it came, but if I were doing it myself I might look for a different spot.

I had a 75gal tank for my gasoline on my truck with the Commercial Emerald 6.5. But then again, I was using the genset most everyday for at least 10hrs a day. My first genset went 12,000hrs before it gave out-and that's without ever removing the head to decarbon it. I always had at least a 1,500 watt load on it (engine block heater).  The 75gal would last about 2 weeks. Lot's of stories about me filling at the gasoline pump on a big rig Diesel truck. Good Luck, TomC

Hey RJ,

Did you forget about the Silversides?  They had the AC motor gas tank behind the LF wheel too.  I saved mine and use it for the Webasto and gen fuel tank.  Works great, 15 gal. cap. on the 3751, I think they were about 20 on the 4104's.

I put a rectangular saddle tank in the front bay of my old MC7. It holds about 80 gallons I think. Bought it from a junk yard.

Make sure you vent what ever you do outside.
