+1 to that clamp.
With my OEM, threads-in-the-band clamp, bits of the fuel line were squeezing through each individual thread opening. The line had a web of hairline cracks, so I replaced the line and both clamps.
The injector side was a bit of a bitch, but manageable it. Assuming your plastic fuel pump outlet is intact, be very careful when working on or around it - it's easy to break, and expensive to fix!
