I was getting warning lights on the dashboard, checked the codes pointed to my fuel system pressure, checked my fuel cap it was loose so I got a new one. The new one is OEM but it wont make a strong seal, it's strong enough to make the codes go away but I feel with just a little wiggle it will pop off. I've cleaned the fuel nozzle going into the truck but that just doesn't help the situation, same issue. Any advice? I checked the ALLDATADIY, see attached. is the gas cap I got. TIA!

Do you smell gas? I think that cap on Amazon is a fake.

Part number is 77300-47010 and MSRP is about $30
There are counterfeits out there. Be sure to get an original, either from your local dealer, or an online Lexus dealer.
eBay/Amazon - it can be hit or miss as to authenticity.

This is the gas cap I got. It looks legit, what do you think? I guess I'll get another one from Lexus direct.

No gas smell but the cap wiggles. When you turn it clicks but doesn't get tight. I posted picks of the actual cap above.

The cap is loose while the base ratchets down

Problem solved, as suggested that one I bought on Amazon is fake (even though it's labeled as OEM) . I went to the Toyota dealer and got a legit one. Thanks all.
