The 950 SE/SMR are near identical, body work wise anyway. The aqualine will work on either 950. Your 990SMR not so much. It may work but you would need a seat for sure, perhaps rear plastic too. I'd be more inclined to carry an extra 1gal bottle of fuel and a siphon tube. You're talking over $1000 to add range going with the tank plus seat plus misc bits.

The dude on the phone thought they would, but he did not sound convincing.
8 gallons of gas would change everything.
