I would guess that you kinked the line somehow when you installed it. The line does twist a little bit when you lower the fuel pump down and position it, so take into account what the position of the fuel pump will be once lowered, and attach the hose to it to compensate. I performed the 'spring' modification a few weeks ago and it went VERY well. The pump was a little noisy when I first started it up, but after about 5 minutes it quited down to a quiet whine. I can barely hear it at all (and that's just because I know what to listen for) from inside the car. It used to drown out conversations after the gas got hot. And with that sturdy spring in there, I know that there is NO WAY for the hose to collapse on itself anymore. I've driven it in 95+ Deg (F) weather and had no problems.
