94 Question

I was wondering where the fuel lines were. I know they're metal, but I can't make them out from anything else. So what side of the engine are they on? Where are they in relation to the oil filter? Which one is the inbound line?

what engine and which fuel injection system? there are two engines and four fuel injection systems. see this link for more info:

why do you need to know? having a problem?

Or you could locate the fuel rails and trace them.

Your best bet probably is to get a manual... it will tell you about the pressure line, return line, vapor line, charcoal cannister (if equipped), etc.

94s have the 4.3L Vortec 4300 V6 with Central Port Fuel Injection

Both the supply and return lines enter the intake manifold at the rear/drivers side. That's also where the fuel pressure checking valve w/black plastic cap (Schrader Valve) is located and it's mounted on the supply line.

Thanks Chris, but since I don't really feel like running out to my car right now, can you be more specific? Like do they connect at the top or bottom of the engine? Do they have any markings or anything to help me tell them apart from all the other metal tubes in there?

The intake manifold is made of aluminum and is on the top of the motor. The back side of the intake manifold on the drivers side has the fuel lines I described. You'll have to look between the intake manifold and the back wall of the engine compartment...also refered to as the firewall.

thanks
