Hump? What hump?

Fuel pooling in manifold
Today while working on the car(84S) I had to remove the air cleaner base/airflow meter combo to have a look at some heater hoses. When I pulled it up, I noticed a bit of gas had pooled at the bottom of the orifice where the airflow meter fits into. What's up with that? I was working on it a couple of weeks ago and had the car running for about 30 minutes or so and may have left the switch on for a bit as well. Would a running fuel pump cause this? Relay sticking?

At base of throttle body, inside at bottom of elbow? If so, common.

Chris If your getting gas in the oil in the intake,
then you have a leaking cold start injector, this isnt good as a backfire could possibly blow the intake apart. I have heard of a few owners having the plenum blow off on an 85/86 32V engine it gets propelled into the hood leaving dents. Usually its just oil sitting in the bottom of the intake

I remember when I took my intake apart. I found a light coat of oil. Always wondered about that. I was amazed how much debris is down in the valley surrounding that area from the last who knows how many years. Yikes.
