Explorer fuel pump connectors

[BroncoRaider]

I’m going to run the frame mounted HP pump when I install the Explorer EFI system. I picked up a couple of connectors to convert to AN line. The black connector seems like it would be more secure with the screw on cap, but there is a a small ridge on the fuel pump outlet that prevents the cap from sliding on. The blue one fits without an issue, but I’ve heard some people caution that they aren’t as secure as the one with the cap. Any thoughts?

Either will work.
