exposed wires in fuel tank
While replacing the sending unti and fuel pump I have noticed that the wiring is totally exposed. The fuel pump that I purchased includes two crimp connectors (similar to the below pic) that also leave wires exposed. My assumption is that the part manufacturer understands these crimp connectors will leave the wires exposed. With this said, how can this setup be safe?? Why isn't a fire guaranteed when current starts flowing through these exposed wires? What am I missing here?

ive always wondered about that a little, because i had to do my pump on my old 2000 chevy and the wires were exposed where they were soldered on the pump. but as long as the wires dont touch (arc) then it will be fine.

That's what I thought
Car companies, Ford included, are guilty of many things but I doubt Ford would follow any practice knowingly that was dangerous, pun intended, they've been 'burned' before - vis a vis the Pinto.
Correction - I HOPE they wouldn't.

According to "field tests" some crazy russians performed - it's not really that simple to set fuel in the tank on fire. I heard about people throwing lit cigarettes into the tank, and nothing happened. I don't think it's a good idea to try it anyways lol. If electrical connection is good - there will be no spark at the connection point. And gas doesn't conduct electricity good enough, so there's no current between wires.

So, while gasoline is a combustible liquid, it's actually pretty hard to ignite, the fumes however........

We'd do it

Where the motor is, there is no air, so while a electric motor will spark when exposed to air, it won't submersed in fuel.
I've seen/heard the same thing. Gasoline is very hard to ignite (the liquid). The FUMES are what typically makes it go BOOM. I've SEEN someone throw a lit cigarette into a small bucket of gasoline and it just went out. Now, hold a lit match or cigarette just over the bucket..... BOOM!

I have thrown cigarettes into cups of gas and it put out the cigarette and didn't ignite the fuel.
