Um, now I'm confused. The hole in the picture is really small - it's just above and to the left (looking at the photo) of the fuel pump. It's no where near 1/4" I don't think. But now I'm also worried because I have no idea what a baffle for this would look like, and if it's not meant for this hole, I can't think where it would go. I'll take another photo tomorrow of the whole block. Maybe I'm making a lot of mistakes? I'm feeling really overwhelmed at the moment. I'll post back tomorrow. Thanks for the help, I'm just not real bright at the moment. Time to sleep.
