Where to find this fuel line?

I have a massive gas leak in my 89 c1500. I circled where the gas leak is coming from. I’m assuming it started because it was rubbing against metal. I tried to put silicone tape seal on it but I think the tension made it 100x worse. I put JB weld on it and it helped slow it down for a bit but now it’s worn off now. I can’t find this line anywhere. Local autopart stores don’t seem to have it. Where can I find this line? I’m tired of constantly having to go to the gas station and I’m losing so much money from this.
