Has anyone mounted an extra fuel tank on the backseat of an Interstate?

[vanavyman]

Has anyone mounted an extra fuel tank on an Interstate?  I can get a good deal on a Firecreek Quick Tank that was mounted on a GL1800 Goldwing passenger seat. Looks like they use the passenger hand grips for the primary way to hold the tank in place.  Since the Interstate doesn't have these  was looking for any other alternatives.  My wife's Trike doesn't get the mileage of my Goldwing GL1800 would love her to have a longer range.  Called a Roadsmith installer to see if there were any options for one installed under the Roadsmith Trike kit but they said not on a Valkyrie.  Could take an extra can but was looking for alternatives when riding in areas with limited gas stations.  Thanks for any suggestions

I've seen people with nice well mounted auxiliary tanks on the
backs of their valkyries, but not ones strapped to the rear seat.

I like the extra gas can idea if extra gas might be needed.

I live in the South and ride in the mountains, so I can get "in
the middle of nowhere" pretty easy, but it would be hard to
get more than 30 or 40 miles from a gas station, so paying attention to
the odometer does it for me... out west I bet there's lots of good
places to ride where you might have to go 200 miles to get
to the next station...

I have an 1800 valkyrie too, and enjoy its 200 mile range. I think
a tourer with an interstate tank and a trustworthy extra can on
the rear rack would make a good long distance 1500...

Thanks for the suggestions Mike, it is nice to have the 200 mile range on an 1800.  I get that on my 2009 Wing.  My Wife's 2000 Interstate with Roadsmith kit gets 22-30 mpg depending on conditions and speed.  Might just be better to carry an extra jug in each bike for her when riding in more rural areas.  Some of those real thick red containers are nice and don't leak.  When we were in Billings on my Interstate we came close a couple times getting real low on gas just cruising around.

I'm not sure, but seems like I remember hearing of one of the vendors that made a belly tank for the Valk. Maybe one of the more knowledgeable members will chime in about this.

One of the members on here has a belly tank, maybe he will chime in.

not one of the more knowledgeable members, but I will chime in anyway. R&M made them, but it looks like they quit making more.

I suspect vanavyman knows about them already.

I have a 4.3 gallon fuel cell that would need some kind of rack to attach it on or slightly above the seat, or even in place of the seat. Gravity feed only. $300. I drain the cell then open the standard petcock for the regular tank. This is NOT a for sale ad as I haven't had it for sale before.

As suggested, a belly tank is an option. $475 and probably the better part of a day installing it. That's after having a brass fitting silver solder/brazed into the bottom of the tank.

There are 2 problems as I see it with the back seat option  1) Mounting the tank. Do you have the regular 1 piece I'state seat? How big a tank are you thinking about? You have to find a tank that will fit in that space. Some back packing straps run under the seat, side to side, might work. I would want something holding it front to back also. 2) How are you going to tie the auxiliary feed in to the  regular feed? Into the tank or a fuel line some where? A valve to turn on and off?

There have been several threads about putting an aux. tank on a Standard or Tourer.

I’m sure there is plenty of room between the wheels where you could have a custom tank welded up. You could just add a transfer pump to refill the main tank if you don’t want to redo the stock delivery system. That would also leave you with your gas gauge. Just a thought.

Not wxactly what you’re looking for, but I remember a post somewhere about a certain gas can that fit almost perfectly into the back of one of our saddlebags.

How about a tank on the carriage rack? I recall a removable tank there.

I have one, but it doesn't exactly fit in Honda bags as neatly/tightly as it shows in these Harley bags. It's doable, just a slightly different angle. They also offer a two gallon can like this.

Replace the saddle bags with Jerry Cans if you want to go all out road warrior.

Why?  An Interstate should have over 200 miles range.  The worst case in this country is a little over 50 miles between stations.  Your reserve should be good for a little over forty miles.  If you're that concerned carry a couple of quarts of fuel in a saddle bag or trunk. 

It's a lot less expensive and covers your need.

After 200 miles I'm ready to get off the bike and walk around a bit.  If I was 30 years younger maybe an extra tank would be good.

Reda. Doesn't pour very well.

Exactly, a one gallon gas can fits in the saddle bags, no problem. And like you said, cost factor.

The only time I need more gas is when touring, especially out west. My saddle bags would be in use for luggage. I like the idea of an easily removable temporary tank on the back seat.
