I’ve always loved the barrel of the F-701. Stainless steel , knurled grip and soft click. But, as much as I loved the barrel I hated the ink. Couple of days ago I took the F-701 out of the drawer and remembered that I had a useless Surari Ink refill from my Surari 0.7 pen that I cut trying to hack a pen. So I gave it a try didn’t even check if it was the same length, put it in , screwed the tip on and clicked! And to my surprise it worked fine!
So to hack your F-701 all you need to do is line up your f-701 refill with the Surari one and cut the Surari refill so it is equal to the F-701 refill.
Here are some pictures : **Click on them for larger view**
Click here to get the F-701 and here for the Surari. You can get the refill only over here, but I’m not sure the spring is included and the spring with the F-701 can’t be removed.
Now you’ve got great ink in a great barrel! Awesome 
^-^ Happy New Year ^-^

Now if only it were that easy with a decent gel refill!
There’s got to be something! I’m definitely on a hunt for that!
