Looking for proper de-pinning tool and plug function

Hey guys,

I'm looking for the proper de-pinning tool and proper way to disassemble and reassemble the plug in the attached pics. This is in a Lingenfelter High Flow Fuel Pump and I need to plug in the fuel level sender unit. The connectors on the end of the green wires look to be the same as what's in the plug already for the fuel pump, but don't snap into place when I insert them in the plug. I'm betting I need to remove the blue piece, but wanted to reach out to you guys before I ruined the plug not approaching this properly.

Thanks,

Sean

Not one I'm personally familiar with sorry Sean. I'd give posting those picture on the Motorsport Wiring Alliance group on facebook a go and see if anyone on there recognizes them.
