Aerostar leaking gas HELP!

I have a 1990 Aerostar 4WD, 4L, with about 120k miles. About 6 months ago I started my van and noticed under it that gas was dripping onto the exhaust at the Y-joint and evaporating. I shut off the van and drove another car to work. That evening with fire extinguisher at hand I drove my car up on ramps and quickly got under it looking for the leak. NOTHING. 6 months later...yesterday. I drove for a few blocks from home and notice heavy gas fumes etc. Stopped the van and again gas was dripping onto the Y-pipe joint. This was an explosive situation... I pulled off the doghouse cover and saw, smelled and touched gas friom on the right top of the engine near the back. My questions are: What could randomly be leaking at this location and is it fixable without pulling the engine.
I pushed the van to a secure location and am afraid to turn it on. Maybe I will drain the gas tank before then.
I am just now trying to find the schematics for the fuel line delivery stuff. Any suggestions on where to go for a manual.
Thank,
Jeff

Not much there but the fuel lines. The fuel rail and regulator that are on the intake manifold.
Where is the fuel filter? Been so long since we had our 89, I have forgotten.

LxMan1,
The Aerostar fuel filter is located under the body attached to the frame just down stream from the gas tank. I found gas on top of the engine block.
I purchased an Aerostar repair manual and am trying to aquaint myself with what is on top of the engine which could randomly leak gas. Also, I plan on buying a C02 extinguisher before I start it up again.
Thanks,
Jeff

It could be a fuel line where it goes into the fuel rail, or possibly a bad injector o-ring.
