Fuel Vent valve - Silly logical mistake

It has been months since I preformed the 15% Super charger pulley upgrade. That was the coolest mod I've done so far.
However for 7 months, since then, I've gotten and reset; an SES light = P0456 (Tank venting system ~ very minor leak detected) occurring every 4-5 start cycles. In my fruitless efforts to figure out the cause for the fault; Googling, determined it was probably a faulty Fuel Vent/Purge valve. Thanks to Pelican Parts and their pictorial tutorial. I realized I had replaced / inverted the "vent canister" - (upside down).


Proper orientation

My erroneous logic assumed the electrical connector should be oriented up. Wrong.
Flipped it around,(electric plug down). No more SES or P0456 fault for the last 2 weeks. What is the logic behind orienting the connection plug in the least in accessible manner???.... Beats the heck out of me?
As long as it works.

Yay for the cheap and easy fix!

So I took the wife and son out for a ride in the Cabrio yesterday. My son has never ridden in a rag top before so I stop at a stop sign and go to drop the top. It comes back to sun roof but then the top will not fold down. I'm like what in the world??? I had no idea why it would not go down, well there are 2 arms in the back that have to be folded down and one of them pushes a switch to allow the top to fold down. New owner error!!

I come here when I need answers. I’ve never needed to post a question. I am well versed in searching before asking so I’ve never bothered to create an account. Until now, specifically, to reply to this post.

THANK YOU!

and now back to where I came from.
