P0457 code... i swear my gas cap is on!

I was replacing the gas tank skid the weekend before last and managed to break my fuel pump in the process. So I replaced the pump last week, and a couple days later I got a check engine light. So I went to auto zone to get them to do the scan (i just found out about turning the key to get the code) and found its P0457... My neighbor cleared the code with his scanner, and the CEL stayed off for a couple days and then just came back on. I really really really don't want to drop the tank again, so before I do that, has anyone had this code? My gas cap is on more than a few clicks...

Thanks!

Just because its tight doesnt mean its fully sealed. New gas cap should fix it

So you think its just a complete coincidence that it started right after I dropped my gas tank, replaced the fuel tank and in the process disconnected the fuel line and filler hose?

no it was the same code. Bottom line change the gas cap save your receipt if that doesnt fix it then you know its the seal. maybe it didnt seal well or its pinched.. good luck sir

yeah my point was that its a brand new seal... I will try the cap, I guess I could just try one of my friends' caps on mine before buying one. Anyone know if a 97 cap would fit on an '05?

Thanks for all your suggestions
