Wow, what a mixed bag of results and recommendations.

I'm not sure I want to go with flexible tubing as that seems like it will pinch the line or the clunk will get stuck. I think I'm going to add a little more fuel line and try to get the idle downline into the 12-15 second range. I figure that if I'm above idle the fuel is going to go to the back, and I shouldn't need more than 12-15 seconds since that is a pretty long time to fall.

I'll report back if I have any more issues with this.

Thanks,
schu
