4Kq fueling issues

[Shawn Manny]

thats the odd part..after it dies, I can fire it right back up and
it'll idle....but give it gas and blat blat blat...dies...20-30 min
later you can drive it again....there is one inked fuel line in the
engine bay. Can I replace this with rubber fuel line, or just the
kinked section?
