Hard start after sitting. Leak?

[Bobophlange]

Sorry about the limited info. Car is in storage and the issue happened end of last season:

As of the end of the season (October), my 85 Automatic didn't want to start up as easily as it always had. One turn of the key would normally start it. If the cart sat for a few days, it would take alot of cranking to get it to start. Once it was running for the day, it would continue to start up just fine.
I did notice a spot in the driveway on the right of center under the engine after some snow this year. (Gas?)

So, without having access to a great repair manual....
Is there a fuel bladder of some sort that might have a slow leak/crack?
If the fuel pump was bad, would it start at all?
I had a replacement line attached to the fuel rail a year or two ago.
I haven't checked the cold start valve ye. Maybe that?

Any ideas based on what I have access to?

Ideally, I would try to get under her to see exactly were the leak is coming from ( a pic is worth a thousand words). Do you smell gas?

Here are some great resources to get you started

Crank the engine over for a second or two. Turn off and then with a clean dry shop towel, check all the FI hoses and connections. Not sure what line you had replaced but the hoses over time will get tired and leak when they are charged with fuel at 35+psi. The short injector hoses are a usual culprit.
Careful as the starter and alternator are right below the possible leaking fuel hoses. If you do end up changing all the hoses out, make sure you disconnect the battery first.
