Today I finished the plumbing of my 3 gallon AUX tank on my 2022 RTLS. Now, 300 miles before a required fill is achievable. I did not see any leaks, more than I can say for myself. I had a prostatectomy last July. It is gravity feed through the main's vent. The aux tank feeds the main tank via the vent line. The OEM vent line is attached to the Aux vent.
This is the first time I have added an Aux tank to a FI with an Evap system. I would like to by pass the Evap system. I have researched and researched the Evap elimination videos but there are so many theories. I wasn't sure which lines to plug on the 1330. I looked up the install of a Camel aux tank. it was the best. I wish they made one for the Spyder.
If you try this, be ready for a challenge. Space is limited under the plastic. For now I removed the pillion seat and improvised a floor mat to cover where the pillion seat was. I attached two aluminum bars across the pillion grab rails. I secured the bars to the grab rail with U bolts with rubber coating to protect the rails. Then attached an aluminum plate to the bars. My desire was to buy a ragged a%% seat and use the seat pan. I could not find one. I did buy a used pillion seat but it was too nice to salvage. I tried to mount the bars and leaving the pillion seat on but there was not enough clearance for what I had available to use.
I'll try to send pictures. I will also try to up date on how over all successful the install was..
Please do not lecture me on safety, needing to stop often, or alternatives. I have carried fuel containers, I don't like them. I have heard all the lectures. If you have no desire for an Aux tank or longer distance to empty please do not offer your opinions.
I don't mean to be rude but I am tired of the less informed on long distance riding giving lectures or personal opinions about stopping to smoke, or rest their butt, or stretch their legs. I take care of myself on my rides. I rest where and when I want to rest/personal needs. With 300,000 miles in 15 years and 51 IBA certified rides, I think I have it figured out.
Yes, I have slowed down, gave up 2 wheels, but as my brother in law said, I am not dead yet. I am still a Mile Eater.
Here are my reasons for an aux tank:
I travel in remote areas.
I travel long distances within 24 hours.
Stations are not always open at O'dark thirty
In remote areas I have had to pray they have fuel.
I like to pick my places to stop to rest. I hate hanging around a gas station, they are for fuel and restroom, not R and R.
I want to fill the Spyder tank to the 7 gallons.
When I hit a head wind running 75 mph I like to know I can make my next scheduled fuel stop..
I wanted to see if I could do it. Plus I had 3 extra fuel tanks in my garage, 1.8 gal, 3 gal, 5 gal that I have used on previous motorcycles.
) and there's not much space left on the RT that isn't waaaayyy up high on an RT for an aux tank! 
So, I now have a trailer/aux fuel tender. 
If you're still talking about the prostatectomy, that's just TMI for me! 
And what bloody 'aux tank' do you have/wear after one of those operations?? No, don't tell me, I don't wanta know - at least not on the public pages!!
