Hi, I'm looking to purchase the part below. I've purchased the dex 2400s from other vendors thinking it is as pictured here but they have changed the model and it no longer looks like the picture on you website.

    Yes, but I want to add a pressure gauge to my filter. I was wondering if I could use this part to accomplish that.
