I've got a Walbro 255 lph fuel pump. I was looking at it the other day and thought something looked different but couldn't put my finger on it. Then I realized that the hole on the bottom that the screen snaps on to was smaller than my current and last pump. Is that an issue? It's like this one....

Not an issue other than it takes a different sock and tiny JESUS CLIP!!
LOL. Thanks Tom.
