So the 2 front of vehicle circles (2 on the left) come around to the front of the manifold and connect to a tee into one line and run down to the driver side vehicle where it goes into the purge valve with Green connector.
Drivers side (top right circle) goes to brake booster.
Passenger rear fitting(bottom right red circle) goes off to a couple climate control accessories one being a heater valve and other to the rest of hvac system. It has a 3rd line that goes to drivers side rear fuel rail to what looks like a regulator in valley of engine. This is the important line. You can see the top of bolt of the regulator in the last picture.
thank you so much you seriously helped me out more than you know
ive been having this weird stalling out issue whenever i am up in the rpm and quickly cut it out. i dont think i have that line going to the regulator.
im gonna double check
Dont mind the chaffed wires but to me it looks like you're on the passenger side of the engine and on my passenger side of the engine and has a fuel line connected to the end of that rail going to the driver side. Is it possible you have the fuel rails swapped from side to side?
this is the drivers side rear. You can see the regular. Either way hope it runs good with that line connected on your engine
