Hey,

So, I was parked on an incline tonight with the car facing up. When I came back a few hours later, I noticed a gas leak

Not too happy, starting worrying that I had to replace my fuel lines, and I didn't think I can afford that! But it's not.

The leak is coming from the Upper Rear centre of the Gas Tank.

Did a bit of search here and found that my tank may be okay, but I may be having issues with Filler Neck, and/or Fuel Pump. Keep in mind the tank is full as well.

So, now I have a few questions. I'm going to take the tasks of fixing this myself, but I'll need some info first.

I decided to fix the Filler Neck first, because I don't really feel as there is anything wrong with the Fuel Pump.

What are the common symptons of a fuel pump needing to be replaced. I also have a Fiero (looking forward to bring out for the summer!), and when the gas is too low on the fiero, it makes a noise. I can't hear anything like that with the Fuel Pump on the civic.


I looked into my EF manual, and I could only find how to remove tank. But, it shows the Filler Neck still connected to the car. How do I properly remove the neck?

Do you guys just remove the rust from the filler neck, patch it up with it still connected, or just buy a whole new one. What are the chances that the top of the gas tank is rusted, and the Filler neck is okay?

Is there a gasket between the Neck and tank?

What are the costs of a Neck, tank, and gasket if one is needed?

Being lazy question. Do I need to remove the tank to remove the Filler Neck.


Thanks, and any help would be appreciated.

take care.

havent a clue...my black Si leaked in the same place...I just never filled it to full unless I was driving a long distance and would have less than half a tank when I got there...then I parted the POS out!

drop the tank and inspect it...the tanks like to rust up there around the filler neck where it meets the tank...and if thats the case u can fix it with fiberglass or get a new/used tank...also to check quickly remove the rear seat bottom and that gives u access to all that stuff for visual inspection and wire harness disconnection etc.

upon furthin inspecting the diagram its most likely comin from the fuel pump location...they rust out there aswell...basically anywhere that water can collect on top of the fuel tank

I'll be calling for prices tomorrow. I got a 2 Ton Car Jack brand new for $10 today at Zellers. Awesome deal. The regular price is usually $40. Just need the Stands now.

I don't know if I want to user fiberglass, but I'll be calling around tomorrow for prices on a gas tank, filler neck and Fuel Pump.

Whenever it gets warmer, I'll decide what parts to get then.

thanks.

i found most commonly it is either the line entering into the rear compartment or your tak at the seam.
the place of origin is commonly mistaken because the gas tends to travel along the seam of the tank making it harder to find i say if your lines are of poor quality change them same for the tank it will be a piece of mind trust me do it once and be happy do it twice and be pissed.

i was watchin monster garage

I found another gas tank with fuel pump and filler neck that I'll be purchasing soon.

Seller agreed to check it first to see if it has a leak.

Hopefully, that'll solve my problem. It's a decent price, so it's worth trying first.

Don't really want to resort to replacing the fuel lines.

Also, don't want to use Sealent, it just seems easier to replace it.

Although, does the Sealant go into the fuel tank, or applied on from the outside?

Cynikal.Mindset

applied from out side...its like a play-doh that you use to seal up small holes or along the seams when it dries its hard and forms a excellent seal...I've used it on a rad to get home and it was awesome

Be careful the steel lines going to the pump may be very rust. Be prepared to splice some lines. What's good is that there is almost always a good spot to splice it since the lines run inside the car protecting them from the elements.
