Engine Fuel

Where does the fuel line enter the engine?

The vehicle is a 1988 Dodge Grand Caravan. The fuel line is clogged somewhere between the engine and the fuel filter. I plan to use an air compressor to clear the line.
The fuel filter is fine.
The fuel pump is fine, I have turned on the fuel pump with the front of the filter disconnected.

If it's fuel injected, look for a shiny looking 'fuel rail' bridging all cylinders across the top of the motor. You'll be able to discern which way the pressurized fuel enters via tubing from upstream. If your motor is normally aspirated (carburated) then they'll be a rubber hose leading from a fuel filter on the firewall to the inlet of the carb bowl.

Note about compressed air to clear the line-often rubber gaslines appear clogged when they are damaged internally-out of sight. A small flap of rubber can act like a one-way valve, cleaning it won't fix the problem. Since a few feet of rubber fuel line is really cheap, replacement's the way to go if the tubing itself is in question. The insides seldom clog anyway, usually there's a plugged filter at fault. Perhaps your van has more than one inline or cannister-type filter. Check the fuel line routing all the way back to the tank, just to make sure you're not overlooking something simple.
Good Luck!

I put ethanol gas fuel in my car and the engine signal lit up.?

I have a 2007 dodge nitro. After put ethanol gas fuel the engine signal lit up. I filled the whole tank with this fuel. Can this damage my car?

You probably didn't hurt anything, but don't put that junk in your car. You need to read the code to see what the light is about.
