Fuel Tank Leak

Fuel Tank Leak Was feeling up the V today and got to about half a tank and gas start spewing out at the middle back of the car. I also had an issue this weekend where I was on a road trip and my car started making a weird noise in the back by the gas tank then the car sputtered out. After the car cooled down it ran fine but I smelt gas towards the rear end. The occurred after I was sitting in hot Austin traffic for an hour. I towed it back to Beaumont anyways. I know there is fuel pump recall but I'm not apart of it.
Do you think the leak is coming from the recalled plug? I am guessing I'm going to have to cut a hole under the rear seat to take a look
On a side note. My check engine light is on. EVAP error but that has been on since my longtube install.

Earlier this summer during a track event I started smelling gas when I came off track. It only happened then, when everything on the car is very hot. Dealership couldn't find any issues, which I kind of figured would be the case. I went ahead and had them replace the evap cannister and purge valve as a precaution, and the problem hasn't come back at the track events I've done since then.

That doesn't make much sense. Lots and lots of guys - pretty much everyone who has owned a V1 - has had that diff bushing go bad. I've seen pics of ones that basically didn't exist anymore by the time the owner got around to installing a replacement bushing. I've never seen someone have a bad diff bushing result in the driveshaft contacting the gas tank and melting a hole in it. 
Just seems like there has to be something else at play - gas tank isn't mounted properly, rear diff mounts are shot too, something.

Center carrier bearing was replaced 3 years ago by the dealer but I'll take a look at it again. I plan on replacing the diff bushing, cradle bushing, and fuel pump. Anything else I should replace while I have the rear cradle out?

My tank has an aluminum shield in that area so that if the driveshaft does hit the tank it doesn't damage the tank. It looks like you made have worn yours off. I am surprised you didn't hear it hitting. You can get tanks pretty cheaply. I bought one from a salvage yard a while back just in case I have any weird issues. Good luck.

Thanks everyone for the assistance. I took shield off to get a closer look at the tank so it had one. I just purchased and cts tank off of ebay for $120 shipped. Does anybody have a guide on dropping the rear cradle?. Can I loosen the bolts then jack the rear up with the wheels on and roll it out?

Can I loosen the bolts then jack the rear up with the wheels on and roll it out? No, brake lines need to be disconnected. Obviously the driveshaft needs to be disconnected from the diff and you have the suspension components (shocks, trailing arms, etc.). I can't remember what else might need to be removed. If there is an easier way I don't remember it. Maybe someone else can chime in. BTW mine is a thunder grey 2007.

You don't have to take the cradle out. Remove front cradle bolts, loosen the rears and just let it droop. That's how they were doing the recalls anyway...
