Go to Pasco County's website and you may be able to find the info you seek.
Otherwise a Realtor that is a member of the MyFlorida Regional MLS has access to IMAPP TAX and it will show an aerial view with property lines to give you a "basic rough" estimation of where the property lines are. The agent could email a link to you with the info.
If you need the exact lines for a legal matter, you will need to hire a surveyor.
Also if you're considering buying a property that is NOT a bank owned, the current owner may have a copy of their survey and may be able to give you a copy.
Hope this helps.
All the best,
