I believe that with fuel injection, the second tank needs to be plumbed into the main tank because of the fuel pump. The second tank would gravity feed the main tank. On older carbed bikes the second tank could be used via a 3-way valve. You could switch to tank #2 when tank #1 is empty.

To the OP, you need to have a fitting welded to the main tank, then use a quick disconnect to tie the 2nd tank to the system.

 

The BMW shown in the photo in the first link is fuel injected. The suppliers of all these tanks can probably supply suitable instructions. It's as easy to email the supplier as it is to write a question in here!

 

Yes, this thread is old, but I've ran an aux fuel tank on my '09 for years now, and it's worked flawlessly after a few initial bugs. I use a "tail dragger" tank attached to my trailer hitch so the whole tank is lower than the tail light. Bought a factory built aluminum 5 gallon tank, like the one in eglidegoodies, but longer and narrower. Bought it out of KS, and a Google search should provide suppliers.

Used 1" square tubing to build the bracket to both attach to the hitch, and to support the tank. Remember, it's holding 35 pounds sticking out the back of your bike, so strength was important on this. I raised it as high as possible without blocking the tail light, so the exhaust would flow under it.

A sparkless solid state 12 volt pump right near the tank pushes the fuel uphill to the main tank when the main tank is empty. I have a Road King, and removing the speedometer dash exposes a plasic plate where the eglide fuel fill is, and it was very easy to drill a hole and put an elbow there, with the fuel hose running up under the dash with lots of exsiting wires. I'd expect something similar could be done with the eglides.

As the metal tank is bolted the frame via the bracket and hitch, I didn't add a grounding strap as that would be redundant.

It's a common question-causer, and if they are nice I tell the truth; unless it's teenage boys, in which case it's Nitrous Oxide, and they always answer "Kewl!"

 

very nice ! Im impressed

I went with the two REDA tanks in the saddle bags.

1. get gas for the lawn mower 2. help a fellow rider 3.help save my butt 4. strategic extended rides possibly 5. most importantly,psychologically I know I can ride closer to the max limit.

so far REDA doesnt leak but if you get 1 drop on the side of the tanks its going to stink your bags up..which is virtually impossible not to do so put it in a 2 gallon ziplock, and I also keep a small bag of examining gloves(optional).

 

Dam Chart you have guts. Your aux fuel tank is a rear bumper. Plus the weight put out over the rear like that. I don't know... Looks cool as hell though. As a welder I Iove stuff like that.

 

I had one made and mounted it to the left saddle bag guard.
holds 2 gallons but I do have to stop and drain it since it isn't
hooked up to a pump but it has saved my but a couple times.

 

Tell me about those fairing mirrors with the stand offs. Aux tank is pretty sweet too.

 

Now that's funny!

 

Chart, that's an imaginative solution, however I'm interested in your windshield. You obviously love add-ons, so what have you added to your shield?! I've just added something similar to my Firebolt, but haven't come across anything suitable for a dresser.
