Hi there. This is going to probably sound like an obvious reply, but without knowing exactly where on the throttle body the leak is coming from, it’s hard to tell you what might be the source and what repairs are needed. It’s possible that a fuel line was not correctly installed, or may have split or is stripped. It’s also possible that an internal gasket or o-ring is faulty on the throttle body - even a problem with the fuel pressure regulator in some cases. The only advice we can really offer here is to have a second set of eyes come to your location to complete a fuel leak inspection to help you determine where the leak is coming from and what repairs are needed to resolve the problem.
