Heard a guy at the parts counter say never use impact guns on injectors... now I get it

And what happens when that impact gun shock travels up the rail and cracks a plastic fuel line fitting nobody even touched? That's a whole different kind of headache right there.

Man, exactly. That shockwave doesn't just stop at the injector. It rattles everything upstream - fuel rail, pressure sensor, those brittle plastic connectors. Had a buddy snap a return line fitting that way, turned a 30 minute job into a whole afternoon of sourcing parts.
