I was under the same impression concerning the pull pull cables. I believe I read it on the DP site but don't hold me to that. Their explanation was not that the braided cable would stretch but that it would relax, when under pressure with all of the engine vibration, to its full length. This would require re adjustment after your first few tanks of fuel only and gave the impression that it would not be an ongoing problem.
