Fuel pump assembly wiring issue

[Surffer227]

So I wave a walbro 450 hard wired with a relay for 12v. I've been running the setup for about 2 years no issues. I tried to start my car this morning and had no fuelpressure. Chased power all the way back to where the wires run into the tank. I noticed if I move the plastic caps around my pump kicks on. Anyone seen this issue before?? Can I pull these caps off and clean up connections? I don't want to pry to hard and break it and have to get a whole new assembly. https://vimeo.com/184129834

the real question is...where do you get a new assembly and what is the p\n? I have the same 450, i am using 12v to the battery, and a relay for switched ground. but mine is nasty
