Am I missing something? All I see in fusion is 810's and mega 510's. is there a standard length 510 fusion?
I use the 510's for the looks factor, but the 801's, right now at least, are far and away the better carto. I wish my Provari was 801 threaded!
It's a little dirty right now but here's how they fit on an 801 cap.
I like the 801 fusions so much that I'll use a whatever-to-801 adapter without thinking truce about it. I do this, for instance, on my backup car twist pv.
Of course, for my BP I follow 5cs' lead, use a native 801 cap. These are sweet cartos, zero leak issues when used with a good tank.
(I'm slow to change, really like the draw on the 801 fusion.)

Just realized I need xl not regular...... Ordered 20 fusion xl as well as 15 boge xl just for comparison.
I totally agree Frannie. I'm afraid they won't be on this batch coming though. They would be taking time from production and people are getting pretty restless already. The previous batch took forever because of the Mini Fusion tanks which were all difficult to use because of the rushing. I just didn't want to stall on this order either. I'll begin on them when our order ships. My sweet friend over there would stall on the order if we go back into development this late, because she thinks it would make me happy to receive everythingI'd like to see regular length 510 fusions thou the 801 is my first love.
I second that motion.![]()

I understand. I can wait. I'm a forever customer![]()
