I took a video of the leak. Can I just changed the bolt or will I need to replace the entire thing? I tried just changing the washer but that didn't work, lol. 04 ES330

Washer? Isn't there an O-ring on that fitting? The hose itself could be leaking a common problem.

 

it looked like it was leaking from where the bolt is so I tried changing the washer there.

 

Lexus2000 (a highly knowledgeable contributor here) is correct

I don't think I'm explaining it right. I know he's right about the O ring. What I'm saying is I took off the screw here. I changed the washer that goes with that screw. I was hoping I would get lucky and that would stop it, lol.

 

But that link helped. This is the part. It wouldn't tighten when I put it back in. I'll try ordering a new one.

The bolt with integrated washer holds the fitting to the pump it seals nothing.

 

Thanks! I'm dumb.
After knowing that I took the whole thing off and fixed the leak with some of this sealant.
