This particular FPR is just in/out only, it doesn't have a bottom port. Fuelab 54501.

 

Copy, I just looked up the "mini" model you mentioned earlier and took that snip from the instructions it came up with.

 

Wow Kyle good to hear you got it sorted. WTH is that plastic part for with the o-ring? It leads to a filter..? It's positioned well below the fuel feed line that exits the pump..?

I bought a used '05 pump carrier for my car (switched from a dbw carrier for the return system), so fortunately never came across this issue. Talk about a pita but I just looked at an old picture of my fuel pump assembly before install and I remember wondering WTH it's for as well but never touched it. I know on older hondas the carriers never had this piece. Strange but good to hear you figure it out! Too much fuel is a much easier problem to solve.
