strap the fuel bladder on or around all that stuff. i've never put mine directly on the tunnel or the rack i use. all the required gear goes on first and then there's multiple places to affix the bladder since it's not rigid.
it potentially could be mounted elsewhere on the sled.
Just to be clear
This is the unit we are discussing?

Armadillo BagĀ® brings the convenience of super rugged, lightweight, collapsible Armadillo BagĀ® Expedition-Ready Liquid Power Reservoirs to international overland travelers, off-road racers and powersports enthusiasts across the globe. Giant Loopās Armadillo Bags are available in 1-, 2-, 3- and 5-gallon capacities.
Named after the tough desert dwelling armadillo (Spanish for ālittle armoured oneā) that rolls into a ball to defend itself, rugged expedition-ready Armadillo Bags are designed for the safe temporary storage and transport of a broad range of essential automotive and powersports fluids. When empty, Armadillo Bags can be rolled up or packed flat for convenient storage, and they weigh a fraction of rigid plastic and metal containers which remain the same size whether full or empty.
Employing a two-layer construction, Armadillo Bags feature an RF-welded inner bladder contained within and protected by a highly abrasion resistant sewn CorduraĀ® outer sleeve. Webbing and rubber-molded handles provide easy anchors to hang the reservoirs while filling and installing the included pour spout, and to grip the bags while dispensing liquids. Webbing daisy chains run the length of Armadillo Bags to prevent them from sliding out from under tie-down straps. The included plastic pour spout conveniently stows away in a pocket on the outer sleeve.
Each inner reservoir is individually pressurized and tested at the factory, and finished Armadillo Bags are subjected to multi-point random testing and inspections. Although allowed usage depends on local laws, rules and regulations in the countries where Armadillo Bags are being used*, the materials themselves are compatible with hydrocarbon fuels, such as gasoline, diesel, kerosene and jet, as well as coolant, hydrocarbon based lubricants and other automotive and industrial fluids.
