So I went to clean the sending unit on my 05 350z on the passenger side , got it out cleaned it and went to put the canister back into the tank and while putting in the 6 screws I noticed they were not going in tight, I looked and them and all the threads on them some how got pushed in, so i put in Different screws and got it closed up than the next days I got the SES code for small evap leak. Than today I filled up the tank and immediately it smelled like gas. I took a look and it seeped out of there a little bit.

I need a fix and fast can anyone please help me. Thank you

 

No fast fix on this one. You stripped the threads and now you have a vapor leak. This is an EXTREMELY DANGEROUS condition. Get it fixed properly and meanwhile, drive with your windows rolled down and don't hit any electrical switches if you can help it. The worst case scenario is that you may need a new fuel tank and/or fuel pump assembly. Do not try to fix this with some gasket sealer gunk, because you might end up gumming up your whole fuel system in the process. Get a mechanic who isn't going to cut corners on this repair, your safety isn't worth it.
