I'm swapping TPI into a Emissions free vehicle, and need to know what hoses I need to run, i have the u shaped hose running from the intake up to the throttle body on the drivers side, then i have these three http://community.webshots.com/photo/...80117241OSVeZC

on the pass side, the lower one is for the heater core return line ?? I am going to run coolant through no ifs ands or buts, what are the top two fittings for ? Is it just for emissions and PCV ? I think my feed line for the heater core should run from the water pump like my carb'd engine. Right now the TPI water pump is plugged. Thanks
