Default Question about fuel in intake and TB

There is a good amount of fuel in the intake and the elbow and even in the throttle body. I just don’t know what it can actually be. The car is also FI and it has a Vic Jr. with a Sheetmetal elbow. I also have a Nasty Performance fuel system with a Magnafuel pump. Can it be that its running rich? or something else all help is appreciated. Thanks again.

If you have a big cam, there can be reversion in the intake that will blow fuel back up into the intake.

Typically fuel is not noticible as it readily evaporates. Usually it is oil vapor from blowby that is introduced from the breather into the throttlebody.... or if forced induction, oil from the supercharger/turbo can also get in the inlet system.

Are you positive it is fuel only & not a mixture of oil?

It's a little darker in color I'm thinking I have seen it before it might have a little oil in it since I don't have a vac system installed. Ill check the vac line also to see if it has anything in it.
