I got a walbro 190 installed about 2 weeks ago at SLS. Now when I open my sunroof i get a gas smell in the car. I have driven it around with the roof closed and then tried to find any hint of a smell, but there is none. This only happens when the sunroof is open. Ideas? Nick said when he did the pump he looked at the fuel lines and they looked good.

Well there would be vacuum so maybe the air in the hatch is rushing forward. I would check all the connections and look for a leak?
