Nope, it doesn't penetrate, screw acts like a lever creating side momentum on the screw hole' wall.
Also i've inspected body and found signs of the contact between that fuel clip and body.
I know that maybe i'm the only person who've met this issue, but i see possibility of repeating this when fuel clip mounted facing left side.
p.s.: i've run almost whole summer with cracked tank chasing that inconsistent trouble, almost ordered new engine thinking i've ruined my first one, thats why i think this weird rare issue should be here, maybe someone else chasing his tune too
