If it susposed to go from the air filter to the engine, it is called the air induction plenum.

First I would check to make sure you have the proper fuel pressure at the pump - you should have 2 pumps - one that delivers from the tank, and a high pressure pump for the injectors. Make sure that both are delivering properly - you may need to prime the pumps for quite some time if air got into the lines. Also make sure the cam / crank sensors wiring has no corrosion and is making proper contact. Between 0 to 300/400rpm the signal can be slightly erratic until the engine is started so I would not worry too much about that.

I hear never heard of redseal. I do know that Sea Foam at Wal-Mart is the best fuel additive for cleaning out injectors. It is under 10 dollars.

you need to take off the wheel and whel arch to get at this

The fuel tank has lines that go out of it for different jobs. One of this plastic lines helps the gas fumes to breathe out in to the atmosphere throu a filter, so if this line is clogged for some reason no air can get out when you pump the gas in, so it spills it out. Locate this line and replace or unclogge it and hopefully this will cure you problem
