Help! My 86 4runner 22re is leaking fuel underneath the Throttle body. It's hard to explain exactly where it is leaking from, but its squirting out the top of a plastic cap that is upside down. Any thoughts?

 

Well, i found out where the leak was, and took off the plastic cap and a screw came out. I screwed it back in, and it stopped leaking, and held fine while i drove to work. However, when lunch time came, and i started her up, it started leaking again. Could this be some kind of fuel drain that is connected to the first injector?

 

That is called the Pulsation Damper. It helps reduce the pressure fluctuations caused by the fuel injectors "pumping" fuel.

You need a new one.
