Question about 1994 Pontiac Bonneville

1 Answer

Gas line is leaking very close to tank. The leak is at the joint where the metal pipe coming from tank meets a rubber hose that runs to filter. It seems to be leaking right at this joint which seems to have a plastic connector on it. How can I fix this and is it something I can do myself? Thanks, Joe

    The rubber line looks good. The metal line is rusty the car is from Maine. The leaking gas is coming directly from where the rubber hose is over the metal line. I have no garage so its not a problem.

    Hey thanks!! So I really need to just change the rubber hose from the leaking joint to the filter? Is the plastic connector that I am seeing just some kind of clamp holding the rubber line to the metal line? Thanks for any help you can give!!

  • joefl76 Apr 15, 2009

    Just by chance would you happen to know what size rubber gas hose I would need?



    Thanks,

    Joe

    Thanks for the help. Everything went well and I got the leak fixed. I'll let you know next time I have a problem.

    How does the rubber line look? Is it cracked? It may have just split from drying out with age. Is the metal line very rusty? If the rust is real thick, it could have rotted through. Park the car outside, as fumes in a garage can explode easily.

You want to be very careful not to make any sparks while working on this. The obvious is smoking, banging metal tools around, etc. keep cell phones AWAY from the area. Pick up some rubber fuel line from the parts store. Be prepared for some gas leakage, have a plastic pan under the leak. Disconnect the line at the tank, have a piece of new hose ready to push on over the line to as close to the tank as you can, have the end away from the tank plugged up temporarily with a pencil or something that fits snug in it, then remove the rubber hose on the filter, and connect new line from tank to filter, check for leaks, hopefully it is the rubber line you replaced, or the end of the metal line, so the new hose will hopefully cover the corroded leaking area. Clamp and Dry off area and see if you can spot any leaks.

    The fuel line is probably 3/8inch. If it's not a small clamp holding the line to the filter, it would be a quick disconnect fitting. Check at the parts store, they should have different size disconnects for fuel lines. They may come as a set of different sizes (mine were under $10 for a bunch of different sizes,they're just plastic discs really. There should be instructions on the packaging) You can remove the quick connects w/out the kit, but it can be a real pain. I'm hoping there is enough solid metal left between the tank and the filter for this to work. Let me know if you need more info, I'll help out.

    Well Joe, as you can see, I'm no guru on the computer! If you click on 'view larger image' you should see pix of disconnects. These look like mine, there are other versions that look much different, but I'm sure will work fine. From looking at these, your fuel line can be 5/16 or 3/8. It's not expensive since you will only be purchasing enough to reach the tank, it's sold by the foot.

    Great! Good work, thanks for the update! Curt

Why wont fuel go into tank?


Really sounds like someone or something has plugged up your fill pipe. Is there any chance someone has done this?
For a fix, if you will look under the car, you will see a place where the metal fill pipe meets the metal extension coming up from the gas tank. Between them is a rubber hose with a metal clamp on each end. You could loosen those clamps and remove the rubber pipe, and then see if something is plugging that, and where. The gas tank is removable, but both that and the rubber hose will be a "big job'.
God bless your efforts.

My jeep is throwing a code for a vapor leak. ive checked all hoses nothing to seems to be leaking but my jeep has a very strong odor of gas


Your problem is most likely coming from your gas cap. Your vehicle's gas cap may seem tight, but the rubber washer around the inner edge of the gas cap may be defective. Go purchase another gas cap for your car at one of the nearest auto part's location's nearest you. Change the gas cap and reset your vehicle's computer by taking the positive terminal off for a minute and replace the battery cable back on the vehicle. This method reset's your vehicle's computer. If the gas cap is the main problem, your check engine light won't come back on and your problem is solved. Gas is highly combustible and dangerous. always use precaution's when doing any work on your vehicle that require's working with any part's associated with any part's of the gas emission's system including the gas tank, gas cap, purge solenoid, charcoal canister, fuel filter, fuel pump, etc., etc. the gas smell can also be coming from a broken or faulty rubber gas line or the metal clamp's connected to the rubber hose's located between the gas tank fill valve and the gas tank itself. there are several black rubber gas hose's associated with the gas tank. have a qualified technician check the gas emission's system for any and all leak's gas also evaporate's fast, do to the combustibility again always use caution when attempting any and all repair's requiring checking the gas or emission's evaporation system. Sincerely Crystopper.

GAS LEAK


There are many areas of concern for a fuel leak. The fuel tank is constructed of a rigid plastic and is fairly unlikely to leak. The fuel pump is housed inside the tank and transfer gasoline through a combination of metal and rubber lines to a filter in the engine compartment. From the filter it enters the fuel rail on the engine. Any unused fuel then navigates through metal and rubber hose back to the tank. There is also an opening in the tank for the fuel filler.

The first thing to do is establish a general area of the leak. Is it at the rear of the car? Front? Middle?

Secondly, does it leak at all times or only when running? A leak that worses when the vehicle is running would indicate the pressure or return lines from the fuel pump are at fault.

Begin by determining the general area and depending on your ambition and tool resources, raise the car and inspect closer. Be sure to be safe and use a jack stand. On older hondas the leak is typically a corroded metal fuel line or brittle rubber line.

Engine light on smell fuel gas dripping under fuel tank


Engine light on can be a lot of different things. But first, fid the gas leak! The fuel line is a combination of steel and in some places rubber lines. It is likely that the leak is in the rubber part of the line. The tank is usually protected under the vehicle by a steel plate that first must be removed on Jeeps. I don't know what part of the car the gas is leaking from, but if it near the tank at the back, its is probably where the line comes from the tank or where the filler pipe enters the tank. You will just have to get under the vehicle with a flashlight and look to see exactly where the gas is coming from. You may have to remove the bolts holding the tank cover on, it is heavy, so you might want to have a floor jack under it with a 2 by 2 foot piece of plywood between the steel plate and the jack. That way you can lower it to the ground safely. Do the same thing with the tank. You will have to disconnect the fuel filler hose before you can let the tank down. There is a clamp at the tank that hold it on. Look for leaks and replace the hose that is leaking. This is a critical issue. Gas and hot exhaust pipes can set this off into an inferno. Now back to the engine light on. A gas leak can cause the light on because it may show up as an evaporative system leak. It's like leaving the gas cap off. If you want a better idea of why the light is on, drop by an Autozone or Advance auto store and they will usually hook it up to their code scanner for free. Without the code readout you have to just guess at the cause for the light.

Leaky fuel fill pipe


Is it rusted and leaking,only when filling at gas pump? Check where leak is. eg rubber hose or pipe. You can remove and solder pin holes. Kind of old to look for a new part.

Fuel leaks from filler pipe to gas tank


You don't need to replace the gas tank, the filler pipe is connected to a rubber hose which connects to the tank with clamps at each end.

Sounds like you are rusted out. Even the factory parts are not that expensive and they are properly bent. Check the dealer.
If substituting aftermarket piping you want to either replace the bad section with a splice or the whole piece. Notice the end connections and where you will attach the replacements.
Notice the routing of the gas line away from hot exhaust parts and areas a lift jack will crush your line. Notice what moves close to the fuel line to allow for travel.

You may be able to splice a piece of rubber fuel line into a metal line with a few clamps.

I have seen everything you will need at Autozone and Oreillys and similar stores with the exception of Factory parts.
