Hello all,
I too have and still do refill BIC lighters.
You first need to push the pin on the bottom of the lighter in. (too hard to pull out the pin so you'll hear the pin rattle a bit.)
Using an butane refill canister, choose the tip that is the widest to cover the diameter of the hole on the bootom. The smaller tips just waste your butane, so wider is better.
hold the butane canister and tip against the refill hole on the bottom but lean over ensuring the butane comes out instead just the gas/air.
You can feel the lighter become heavier from the filling of butane, fill as much as your comforatble with. ( Don't be stupid and try to fill it completely be rational)
Once filled, quickly put your finger over the hole to prevent butane from flow out of the lilghter.
Apply push pin or tac into hole.
Make sure that it's not leaking, I usually take it over to the sink and fill my palm or small cup with water, submerge the bottom of the lighter (NOT THE WHOLE DANG LIGHTER). Just the bottom and look for tiny air bubbles.
No bubbles= no leak..
That's all folks.
Might I add, that if you have children please don't leave a lighter or matches where they can reach them, Protect our children don't be a dumb ass and leave a modified lighter, the would probably try to pull the tac out.
(BE CAREFUL)
happy lighting
