Here is a picture of the new fuel tank I'm putting on my Hussy. I've already tested the pump, and will soon be carrying another 2.0+ Gallons of useable fuel. The MSR bottle is for fresh engine oil which often needs a change on long rides.

I'm sure the workmanship is good but not sure I like it because it's in a vulnerable position and you're loosing the additional clearance at the front of the engine which is one of the benefits of the 70 degree engines IMHO. Mind you, depends on the type of terrain you're riding.

Hope it works out well though.

Ok, you have a couple of valid points. I thought of those before I built this. Here is why I decided to go this way:
1. The weight stays down low, keeping the bike balanced,
2. The husaberg with luggage gets weighted to the rear and this moves some weight forward,
3. I selected an aluminum with a 44,000 PSI tensile strength, which compares with 1/8th inch steel,
4. I've never holed an skid plate yet in my life, so I figure this will probably survive
5. I couldn't afford the cost of a Safari Tank, and this will be less than half the cost.
6. I can loft the front a little higher if I have to.
7. I can also remove this whole tank skid plate combo in less than five minutes. I designed it as a unit with the fuel pump. All that stays on the bike is one fuel line and a petcock, the rest drops off with the removal of five bolts, one vacuum line, one vent line, unplugging the fuel delivery line and placing a vacuum plug on the vacuum port.

Anyway, that's my thinking and why I went this way.

The only real downside I can see right now is the extra width. I ride some rough back country, but because I get so far into the back country, I don't try to be Graham Jarvis. Medical is sometimes days away from my location.
 
Great idea! I like it.
Can you post some photos of how you fabricated the back part that hooks up under the frame?

When I have it finished, I'll add some more photos and include my fuel pump set up, probably w/in two weeks.
 
It's the plumbing that interests me. How you get the two tanks to work together, how you prevent the factory tank from continuously draining into your auxiliary tank, and how you get fuel from the auxiliary to the fuel pump.

I already have a 70 Degree tank. The fuel will be tapped into that tank in the top, not into the main tank. I am using a pump, to transfer the fuel. The line from the pump to the tank has a petcock in it, that will remain shut until the low fuel light comes on. After opening the petcock, the pump ratio is 14 liters per hour, so I should have no problem refilling the 70 Degree tank which cross feeds to the main tank already. With the solo petcock closed, there is no other connection between the tanks. Also, with the pump and the line to the top of the 70 degree tank, I don't see too much potential for siphoning. As to the transfer of fuel, I've built pickup tube into the tank which has been welded in front of the engine. From there, I have a line running underneath the engine to the fuel pump that I have placed in the void behind the engine and in front of the shock. I bent a 1/4 inch steel vacuum line running from the pump up to the vacuum port below the injector. I cheated the pump to one side away from the exhaust, and I have run the delivery line up the same void as the original fuel line to beneath the seat where I T it into the 70 degree tank. Like I said, I'll post a detailed set of pictures when I have the install completed. My welder has assured me, he'll be finished by next Thursday. By the following Monday, it will be polished, installed, and operational.
