Cannot find fuel line connector

[FrankT99]

I bought a new fuel pump for my 2003 Ford Explorer Sport Trac but can not find the right fuel line connectors. That are two different sizes (see images).
Which connectors do I need and where are they available?

So you broke the fuel lines on the truck side of things?

The new fuel pump / tank assembly should match the old one, otherwise it’s possible they sold you a 2003 exploerr pump not a 2003 sport trac
