346xp leaking fuel

previous owner says the saw always leaked gas. fuel lines looked tired so I started by replacing them. found the tank vent had backed out of where its seated in the tank. rattling around in there it had oversized the hole. so I put that in with some sealant and figured it was good. wrong! still leaking gas like a sieve.
the main feed line from the filter to the carb isn't making a seal where it passes into the tank.
is there supposed to be a seal there or is it just the outside of the fuel line pressing against the orifice? does OEM husqy line have a different outside diameter than the generic stuff I got at tsc? any thoughts on how to seal this up?
thanks in advance.

Hi I have fixed several huskys that leaked where the fuel line comes out of the tank and yes there are several sizes of generic fuel hose. The way I fixed them was putting a stihl weedeater gromet in the hole then run the fuel line through that,it seals them tight. I had a 350 that I fixed that way.I drilled the hole just big enough to get the gromit in run the hose through it no more leak.
