Leaky fuel line

[drdave69]

I sent my qjet to Eric for rebuild and needed to replace the fuel pump to carb after I got it back. I installed the new line and is leaking at the fuel pump fitting. I refitted it two more times and it is still leaking. I lifted the front of the car to try to get the fuel from flowing to the fuel pump for now. I have not started the engine yet with the new line (for obvious reasons) so I don’t know if it will be leaking at the carb. It was leaking at carb with the prior line and that is why I bought a new line.

What is the best way to solve this issue? I have considered getting a stainless flex line with AN fittings if that will fix this problem.

This is on my 70 Monte Carlo with LS5 454.
