1996 Dodge Neon. steady gas leak, basically emptying the tank in a few hours. The car wasn't used for about a year, put about 5 gallon in an empty tank, and i immediately noticed significant leaking around the center of the car. possibly closer to the back. Previous owners were doing minor work to the car. I'm wondering if they installed something incorrectly?? Could it be something as easy as a fuel filter?? *hoping*

Sounds like you might have got a bad batch of gas, it happens. I would go to a different gas station and put some high quality gas in it and also add a can of heat to the tank. This will evaporate any water that might be in the gas tank.
After running a pump dry you can start to ware on it and even ruin it if you try to engage it with no gas. Also it is possible from running the tank almost empty that sock on the fuel pump was exposed to more than it's fair share of contaminants. A little more fuel in the tank might help a bit.
Might want to change the fuel filter if it's been a while too. The fuel filter gets might clogged after a while. It's an easy hob to replace and is cheap and necessary about every 15,000 miles.
I assume you don't have a check engine light on or you would have put that down.
worth checking the fuel tank for holes or there might be some fuel delivery pipes leaking badly. Or it might be an O2 sensor not giving correct signal to ecu thus consuming so much fuel.
Hi,
Not extremely hard, but it is in the fuel tank, so you will need to be able to jack the car up at least about 2 feet and support it on jackstands/blocking. Takes about 2 hours. Steps:
Disconnect negative battery cable.
Make sure transmission is in park and chock both sides of front tires.
Raise and support vehicle.
Siphon fuel from tank, make the tank as empty as you can.
Loosen the tank support straps but do not remove them fully yet. (use a bunch of WD-40 or liquid wrench on strap bolts to facilitate removal)
Disconnect the feed and return lines and electrical connector from the tank, then support the tank in the center with a block of wood under tank and a jack under the wood.
Remove the passenger side support and carefully lower the passenger end of the tank.
You should be able to lower it enough to access the round pump retainer ring, gently tap it loose.
It will be a tight fit but you can maneuver the pump out now.
Clean the ring and tank mating surfaces. Swap the pump , reverse procedure to re-install.
Doublecheck all your fittings/connectors.
IMPORTANT: replace fuel filter at this time, I HIGHLY recommend it!
Lower car, reconnect battery cable, put 1-2 gallons of gas in tank.
Turn ignition key to run (not start) position. Listen for pump to be running.
Allow 30 seconds for pump to prime the fuel rail.
Check for leaks.
Start vehicle, allow to idle, check again for leaks.
I usually test the fuel pressure at fuel rail or TBI unit before assuming the new pump is good, I have gotten a few bad ones from the parts store. If you are going to do that, do it before you lower the vehicle in case you need to remove the pump again.
Sometimes that little metal flap that was covering the hole where you put the gas can break and fall in. causes a blockage. Another thing, i used to have a Buick Regal that i had to hold the gas nozzle hard to one side and pump really slowly to get gas in. If all else fails, get a 5 gallon plastic gas can, fill that up, then poor it down your car gas tank. Alot of work, but its cheap.
We needed our heater core replaced and got estimates from 600 to 1500 dollars from the dealerships. you will basically have to tear the entire dash apart and then some. we found a guy to do it but when he finished he said if it happens again to find someone else. My husband wanted to tackle it but I wasn't willing to put up with the throwing of tools and hours of btchn. Unless you have the patience of a saint you'll want to take this one in.
on a dodge neon the fuel pump is in the SIDE of the tank... NOT the top. to remove the pump follow these steps... ******* first unplug battery and remove ******** 1. unbolt passenger side tank strap and lower side of tank. 2. a. if tank is plastic, CAREFULLY unscrew plastic retainer ring but do NOT remove. b. if metal tank, unscrew metal retainer flange but do NOT remove 3. unplug electrical connector and fuel line from pump. move aside. 4. completely remove retainer BE CAREFUL not to disturb pump. 5. have drain pan or wide-shallow bucket available to collect gas. (if tank is full this will need to be able to hold 7-8 gallons) 6. gently twist and pull pump out till gas comes fourth. catch gas in pan/bucket. 7. remove pump when gas stops flowing. 8. install is reverse of removal. 9 BE CAREFUL not to wrinkle gasket or lose gasket into tank when installing or the tank will leak around pump. 10. tighten retainer but DO NOT OVER TIGHTEN. 11. reconnect plug and fuel lines check for leaks. 12. reattach tank strap and fasten 13. refill tank with clean gas. check for leaks. 14. put battery back in. connect battery, start your neon and check for leaks one last time. 15, have fun. this will take about 4hrs to do by yourself with proper tools.
there is a flexible rubber coupling between the tank and the filler nozzle .. thats the most likely thing to have been damaged .. check the clamps at both ends and replace the rubber tube if its bad ... if not then there could be a hole in the tank maybe caused by a rock hit (sometimes rust) ... there is a special epoxy stick that works with gas (any auto parts store) .. you can patch a small hole in the tank but not in the flexible coupling ... of course you should fix this before something bad happens ... run the tank near empty if you plan on taking it to a garage for repairs .. the tank is too heavy loaded with fuel ..
hey
at the begging u should clarify how many gallon u used.
112 miles at 28 miles per gallon --> 4 gallons burned (112/28)
So that means we leaked 11 - 4 = 7 gallons
Now figure out how long the car was driving.
112 miles at 64 miles per hour --> 1.75 hours
So, leak was at a rate of 7 gallons in 1.75 hours
7/1.75 = 4 gallons per hour leaked.
