Fuel Pump

I was working on a fuel pump this weekend. It's not a DSM but I'm sure people here should be able to tell me something about this. Went to help my sis with her car that's been sitting for 6 months because it couldn't start. It's an 89 Chrysler New Yorker. I found out that the fuel pump was bad. I installed a new pump and now it starts up perfect and runs normal. This is the first time I've really mess with the fuel pump in a car. The thing I'm wondering is that the fuel pump installs into the fuel tank and there is 2 wires, a black and red. The two wires connect to the fuel pump via quick connect female blade connectors. Ok these two wires that connect through blade connectors are just out in the open. I thought that was kinda scary. Could the connection ever cause a small spark when power is fed to the fuel pump? Wouldn't that cause a big fire? Or how about if the gas splashes around all over the two connectors. Wouldn't that cause the power wire and ground wire to spark or ignite or send current through the gas causing it to light up? I got scared thinking about it but that was the way it was when I took it out so I figure it's ok. I still can't stop thinking how it doesn't ignite the gas. Can someone explain. Is there something I don't know.

Did you have to drop the fuel tank to get to the fuel pump?

Wow where did you get those pics from? The one that says turbo and V-6 is the same exact one I pulled. There is even a sticker above the power plug that says turbo and V-6. Well it would be easier to pull the fuel pump assembly out if I droped the fuel tank down but it would be a lot more time consuming. I was able to get the fuel pump assembly out without dropping it down all the way. The assembly goes in from the side instead of from top. Now is there something I don't know about igniting the gas?
