dolmar 153 oil line problems....cuttinscott?

[MOE]

I've got a poulan 6000 version of a 153 dolmar. I replaced the oil lines a year ago and struggled to get the lines in place without kinking the one that goes to the pump. Well it's not pumping again and it looks like a kinked line is the culprit. Is there some stiffer line that is used or a tighter T fitting off the oil tank? Thanks
