I filled up the zforce 800 pretty much to the top while it was in the garage. There are no leaks or fuild spilt.  Few days later I backed it out of garage and had in the parking lot. Then seen some fluid under the sxs. It was gas, I now have driven in about 20 miles and keep smelling it. I think it exspanded and some came out the overflow when I brought outside. I don't see no more fluid but still smell gas while driving it. Any ideas? 

pull out the passenger seat and seat if it is wet around the fuel pump sending unit. Mine is leaking there, I haven't gotten it to tighten up enough yet to not leak. I am going to try one more time and if I can't get it, off to the dealer it goes.

Mine was the same at first....throw a twist on the large cap and it should stop.
