1990 civic gas tank leak

Discussion in 'Civic' started by 'Curly Q. Links', Nov 24, 2005.

    The reason the fire department tells Honda to tell it's owner's to stop
    overfilling the tank has just appeared on your driveway. YOu can get
    owner's manuals from the wrecking yards, and Honda still has many of the
    old ones available.

    If that fuel had gone down a sewer cap, the outcome could be very bad.

    Fuel is very cold when it comes out of the ground at the gas station,
    but it expands a lot as it warms. That's why it's illegal to overfill
    your tank. You're not a smoker, are you? :-(

    Filled up the tank yesterday right to the top around 6pm and then
    parked the car later that evening indoors about 11pm. Today at 2pm I
    had a puddle of gas about 1m in diameter under the gas tank by the
    driver's side rear wheel. (I was parked on a level surface).

    I've never experienced a gas leak before, but have a feeling its from
    the tank. Could it be that I just overfilled the tank right up into the
    neck and that a seal there is starting to go? Should I replace the
    whole tank? Any other ideas what could be causing the leak?

    Thanks in advance,
    Theo

    thats news to me, and i think ive read my owners manual front to back a
    few times. isnt that just a general warning? or something especially
    specific to hondas? hondas of that era?
    not just that. if they had parked in an enclosed garage with a natural
    gas water heater or gas clothes dryer, that would have been a big problem.

    I noticed that mine leaks when full only when the front end is on
    jackstands. I assume a leaky filler tube. I had no idea it's common to
    all Civics.
    This is why building code mandate that burners of gas fired appliances
    located in garages need to have their burner at least 18" above floor
    level.

    The funny thing is that this is the first time I have noticed the leak.
    The only other contributing factor would be that my garage is heated
    (underground in an apartment building), and the temperature just
    dropped here significantly as well (around -15°c).

  6. If the car has been driven in winter conditions often, the tank and or
    parts of the fuel lines may be corroded and leaking. It happened with my
    '93 Accord a few years ago. So take it to a mechanic who specializes in
    this type of maintenance.

    current building codes. i dont think it was ALWAYS that way, but it may
    have been.

    Illegal? where? Certainly not here in Texas.

    Call your fire department and ask them.

    In Alberta it's illegal to put gasoline in a glass jar, an antifreeze
    bottle, a bucket, etc. The gas stations can get in BIG trouble if they
    let you do it. Same thing if you jam you pager in the pump nozzle to
    allow you to go wipe your windows while the tank is filling. (some
    stations don't have the 'latch') I'm sure it is in texas too.

    really? in california, we have signs at all the gas stations saying its
    illegal to dispense gasoline into an unapproved container, yadda, yadda,
    yadda....

    only makes sense.

    I've seen similar in other states: Stations won't sell you gas unless it's
    in a certified container.

    Curly's explanation about why drivers are warned not to overfill gas tanks
    is the first I've seen that makes any sense. Nice to have a reason not to go
    beyond one click now.

    We have signs in Texas as well about dispensing into unapproved containers,
    do not get back in car while pumping, turn off cell phones, etc. I have
    also occasionally seen topping-off on the list of do nots. I have yet to see
    anything that says its ILLEGAL to top off. If it is, then I estimate
    somewhere around 99% of drivers using self service gas pumps around here are
    breaking laws.

    As I understand it, the manufacturers recommend against it because it can
    back flow into the charcoal canister and mess up the EFE system (You will
    get a "check engine" light if this ever happens). The EPA doesn't like it
    because the little bit that spills on the ground can evaporate into the air.
    Any explosion risk that might be there is from static sparks and is
    addressed by the "do not get back in car while pumping gas" admonition
    (which is also rampantly ignored).

    The thing I am taking issue with here is the assertion that it is illegal to
    top off. If that were the case, then self service gas stations would have to
    be eliminated, since the station owners would be liable for any law breaking
    done using their property.

    I'm guessing you're not going to phone the fire department, right?

    If I cram 60 litres of ice cold gasoline into my CR-V (so there's no
    room for expansion in the tank) and park it on the street in the summer,
    where are you expecting the excess will go when it expands to maybe 64
    litres? Down the nearest sewer drain? That's the kind of calls the fire
    department / hazardous materials team LOVES to get. Where will the city
    send the bill, and will the TV station show my license plate # on the
    six o'clock news? Will they mention my name? It won't be me getting
    caught.

    No, I'm not going to call the fire department. For one thing, they are not
    responsible for enforcing any laws.

    I did just come from the gas station though. The pump has warnings printed
    all over it. I took the opportunity to read them. Everything you can
    imagine is warned. Nothing about topping off.

    I can't remember the TV news ever focusing on the fire department responding
    to a dripping car. This whole fire department thing is just silly.

    I have lived in Texas for over 30 years. Consequently I know something about
    fuel expansion in the summer. I have never seen four liters of expansion
    pouring out of a car. In fact, on all four of my current cars ('91 240sx,
    '96 I30, '00 TL, and '02 Pathfinder), the pump clicks off within 2 tenths of
    a gallon of what they hold when filled to the top of the filler neck. If
    its going to expand by 4 liters (essentially a whole gallon), not topping
    off isn't going to help. Perhaps you are overestimating expansion?

    It may or may not be ill advised to top off a particular car. I have never
    seen anything (except your assertion) that has ever said it is illegal to do
    so. I guess its possible that it might be (illegal) in Canada. Different
    country. No evidence of it here.

    I'll check with a (veteran) fireman I know. Maybe breaking a 'bylaw'
    isn't the same thing as illegal.

    Yeah, you do that. Other than arson investigations, I have yet to meet a
    fireman who enforces any laws. It just chafes me when people start getting
    so self righteous that whatever they personally decide suddenly becomes
    "illegal" for everyone else.

    It might be illegal to pour raw gas on the road (if not, it should be).
    That is not the same as topping off.

    Even at that, you live in a different country from many of the rest of us.
    What your laws may or may not be is irrelevant to those of us who don't live
    in the same jurisdiction.

  18. That's been the case in the 3 states in which I've lived.
    This is an especially interesting thread for me because I live in NJ
    where it's illegal for drivers to fill their cars (I am not making this
    up). IIRC I first saw the warning about not topping off when gas
    stations went to vapor recovery equipment, i.e., it's mostly an
    environmental concern. Some stations in NJ still top off, although most
    let it run until it kicks off automatically & remove the filler then.

    Topping off one's tank early in the AM (or otherwise filling with cold
    gas) and parking without driving much could cause a puddle of gas as the
    cold gas expanded as far back as I can remember (certainly during the
    70's with non FI engines). One poster mentioned cold temps with a heated
    garage, thus ensuring maximum expansion.
