I am currently living in a house i am about to purchase., last week we discovered a fuel smell in the living room. We found that there has been a slow leak for quite some time but was made worse when the discovery was made and a nail that had been driven into the pipe was pulled out. the boards of the house are drenched in fuel out and Im guessing theyve been saturated for quite some time since the construction happened in that room over 2 years ago. When the nail was pulled out the leak was so bad that it went outside the house and leaked onto the concrete foundation. It is also on the foundation in the livingroom under the floors (that had to be taken out and replaced since some of that was saturated as well. I dont know how much fuel oil has leaked there but it must be quite substantial. What I want to know is if this is dangerous? I am worried about a little spark setting my house into flames like nothing. And also any further damage that it may have caused? I dont know if I should even purchase the home now, as i know nothing about this and I dont really want to live in fear forever.

if anyone has, ANY advice about this I would appreciate it. I dont really have anyone to ask and to turn to so I needhe all the help I can get. Thank you
