Can't unscrew the fuel line bolts

Hi all,

Ladies and gents, I'm experiencing pretty tough situation - i need to remove the fuel line from my Street Triple but for some reason those bolts are sitting insanely tight.
After several tries the screwdriver sitting place is almost destroyed. WD-40 doesn't help.
Now i really don't know what option should i try? Can i use impact screwdriver (wouldn't it damage the throttle body)? Or just make a thin cut on the head and try with flat screwdriver?

Soak it with a good penetrating oil (WD40 doesn't count), let it sit overnight. Use an impact driver, but just rap it firmly - you aren't trying to swing it over hand like Thor's Own Hammer!

If this doesn't work, you can either slot the head or drill it off; once the rail is out of the way, there's plenty of room to grab it with a small Vice-Grip.

Those screws in the picture look like they have a little punch mark (dot) on the heads, If so, those are JIS screws not Phillips. I have several sizes of Vessel Impacta JIS screw drivers that work great on these types of fasteners. They look like regular drivers but have metal end caps and work as impact drivers too. Amazon and ebay sell them, I have the #2 and #3 versions.

Screwdriver socket with a ratchet.

The sooner you introduce motorcycles into your children's lives, the less likely they'll have money for drugs, alcohol and cigarettes as teenagers.

Worst case as it's a long bolt is drill the head off, and extract what's left.

Hated removing mine, but made sure I put copper slip on them when they go back in.
