    Yes, sir. She's been working fine with no leaks since I did it.

    I guess I'm taking an action to replace the pump too! Thanks for the DIY!

    I sprung a leak on mine as well but definitely on the reservoir side. When I drove down to Sigfest, my reservoir was full and it was full when I got to Williamsburg. After the drive, my reservoir was empty and seems like its leaking from the nozzles. But both nozzles?

    Bad cap maybe?

    I think David had a problem where the cap wasn't releasing pressure.

    When the tank heated up the increased pressure drove fluid out of the nozzles.

    I wish this was sent with a Galaxy S3

    Hmmm interesting. I will check that. I just replaced my cap so that could be the case.

    Yeah...cap didn't hold pressure (was leaking) so fluid didn't pump correctly.

    Thanks for the writeup, I will definitely be using this when I fix mine this week. So, is it typical to replace the pump and grommet when doing this just as a safe measure? Mine looks like it is dripping from the pump and onto the grommet, but I have to look a little harder at it. Considering it is only $20 for the pump I might as well do it, ay?

    Awesome DIY. Glad I found this. I came out to drive to work this morning to find washer fluid all over the garage floor.

    That's how I looked at it. Cheap enough to just bang out both. Lord knows if it was one, the other would start leaking a week after I had it all apart.

    From what I read they are both common failure items so it made sense to me to just do both.
