Before anyone gets all flustered about using the search for the forum I did and really didn't see anything like this before.
Short story short... Just had the car shipped up to NY from Florida on an open trailer hauler. Shipper stated that they wanted less then half a tank in the car, so my father siphoned the tank down to less then half and drove the car to meet up with the truck to have the car taken away, about a 2 mile drive.
Shipper loads the car and takes off like he should. Calls about midway through and states the car is outta gas.. Car arrives here in NY and drops it off at a gas station. The car had half a tank but wont run. I put a fuel pressure gauge on and no pressure, so I pull the pump and this is what I find.
Order a new sending unit and put it in and go. You can purchase a new sending unit with a pump already on it. That would be my suggestion. Looking at that plug and looks like it arced. That gives me goose bumps thinking about an explosion.

That's what I was thinking. I know you can test the pump by using a 12v source, but should I assume the pump is toasted?
I've learned a little about the tanks of tanker ships and I know there is a lower explosive limit (LEL) and an upper explosive limit (UEL). Assuming you can treat the gas tank of car the same way, since there is mostly fumes from the tank in the open area of the tank and very little oxygen, the mixture is not in zone for it to be 'dangerous', regardless not safe on bit.

I see most of the normal sites have the units with or without the pump. Is there any way to just order the harnesses for both sides of the tank? The fuel gauge was working when I took it out but the fitting that sits on the outside of the tank was slightly charred. If needed I could buy a whole new sending unit, but I'm a college student on a budget.

budget or not, do you want something that sparks/burns in your gas tank??? making up the wires is easy....just use the same guage and connectors....I'd think about it though.....we'd like you around for the next semester....

I think I understand what you are saying. But correct me where I am wrong, the metal frame and tank top is the cause of this and not the harness with the wires?
can't really say for sure....I guess a bad connection could do that....I was thinking it would be the pump itself....I guess you could put it back together and test it before you install it. Did you disconnect the neg battery cable before removal?....probably a good idea...get your education about static somewhere else....

Ok. Yes the car is currently without the battery connected, and I've sealed up the top of the tank with a plastic bag and duct tape to keep crap from falling down in. I'll get the sending unit and a new pump ordered tonight.
Whats the deal with the sites selling units with pumps for 319 and then units without pumps for 170.. You can pick up a pump for 90 and be done at 280ish?? Am I missing something?
If you have a poor connection the high resistance will cause it to heat up (Ohm's law: P = I * I * R). That will melt the plastic of the connector (very common problem).
The voltage in the tank is far too low to arc to anything. The general rule of thumb is that it takes 25,000 volts to arc 1 inch in air.

I ordered a whole new sending unit and pump from Rockway Auto. Pretty good deal. I'll keep everyone posted.

My guess is that the battery has been pulled way down. I jump started the car initially and ran around for an hour trying to place some charge on it. Should be alright?
