Car has been on jack for couple months waiting for suspension rebuilt. I started car yesterday and notice a puddle near front driver side wheel, it smells like ethanol so I guess it's my fuel. It looks to me the one I circled in red is leaking but not 100% sure.
Need ideas on what is leaking and how to fix. I included pictures and one video. Thanks in advance.

 

Ensure the injector seals are not leaking. I had a large pool of ethanol under my car & found that one injector lost its seal during startup

 

My injector was installed by a shop and I have not messed around with them. The leaking is in the area right behind the battery. I don't know what line is it.

 

looks like your supply line is clamped with two hose clamps.

its probably leaking right there

 

Thank you sir. I tried to tighten those two clamps and now it's leaking even more. What exactly is this line?

 

Looks like you had an Ethanol sensor added into your fuel return line between the rail and the chassis. The line they used to connect from the sensor to the hard line appears to be what's leaking. I'm guessing it's too big for the hard line based on the attempt to double clamp it. There really shouldn't be that much back pressure on the return side though, you might want to look into that too.

 

if thats the return line... i would just try replacing the hose.
