Replacing fuel pump. OEM part is PRC8318 for reference. Replacement is easy enough, but wanted to know what the oval part is above the pump - looks like a miniature brake fluid cover. Is there anything to rebuild or check there? Thanks

 

Are you going to replace the assembly? It's very cheap. I wouldn't waste time trying to cobble together one of those just replace the pump portion fixes for this job.
