I have a 1991 softtail. When I fill the tank up petrol leaks from the tank somewhere between the two sections of tank. Is there a tube or some sort between the two sections of tank. How do I take the tank off as I am a novice Harley owner?

Hi, have a look at the bottom front of the tank, you will see a hose going from one side to the other side tank, check and see where it is leaking, you might have the original crimp type clamps or the adjustable clamps. If its crimp type get a mechanic to help because you can do damage to the actual metal lines, if its adjustable try tightening them up, if not, screw the clamps off and replace with new ones, you can unscrew the new clamps all the way and gently stretch it open so it slips over the hose, make sure you lline the housing of the clamp and the flat part which screws in straight. If the hose is leaking than take the hose off at the on/off tap and drain fuel, will take a while but its the easiest way unles you want to syphon it out, when the fuel is very low than you can take the hose and clamps off at the front and replace them, straight forward. You can also park the front of the bike up a hill/or similar so the fuel sits at the rear end of the tank.

Our commode isn't leaking, yet it refills many times a day

If your commode is refilling over and over, you may have a Ghost Flushing problem. Even though there's no water on the bathroom floor, you likely still have a slow leak somewhere in the tank. To locate and identify the source of the leak fill the tank and shut off the water to the commode. Remove the tank lid and draw a pencil line along the top edge of the water line. Leave the water turned off and go back several times and redraw the pencil line at the water line. When the water stops draining see where the water level is. If the water has stopped just below the overflow tube, you likely have a siphoning problem. If the water drains to the bottom of the tank you likely have a flapper problem.<br />To correct the siphoning problem reset the the depth of the fill tube in the overflow tube. Fill the tank up, shut the water off, and recheck after some time. Repeat these steps until the water stops draining.<br />To correct the flapper problem gently lift the flapper and clean the bottom of the flapper and the flapper seat. Refill the tank, shut the water off, and recheck later. If water still leaks replace the flapper.

Hi,I have a 98 EL falcon that when I put over 3/4 of petrol in it, it will leak somewhere and fill up the well on top of the pump,only does this when over 3/4 car runs well?

i am thinking that the seal around the pump / fuel gauge is faulty and the extra fuel level up the hose is leaking out
it could be the fill hose to the tank has perished and cracked leaking the fuel out or the clamp is loose
what ever it is imperative that you fix the fault quickly as loose fuel is dangerous

My gas tank on my 1987 Dodge Dakota appears to have a leak somewhere at the top and the front side of the tank is slightly wet from the leaking gas. What could be causing this? How difficult is it to...

it may be the plastic/rubber fill tube, this attached from the top of the tank to the fill with a hose clamp at each end. If you climb under the side where you fill up from and look up you will see it, as it resembles a radiator hose. Good Luck Tim

There is petrol leaking from the overflow on my zxr 400, should this overflow be connected to anything else via tube ....?

No, the overflow tube should dump the fuel out the bottom of the bike.

Possible solutions (?): 1: Don't over fill the tank. 2: Check for corrosion in the tank overflow tube.

I inherited a 2004 BN125 that now leaks gas when started from tube that is located next to battery overflow tube

If overflow tube is leaking its due to too much fuel in petrol tank or could be a loose fuel pipe make sure its an overflow pipe not a fuel pipe just leaking

Petrol (gas) inlet is very slow it seem like an airlock have somebody else had a simmilar problem

Yes it's a common problem. You have two options: 1. fill the tank very slowly or; 2. (more tricky) put a short length of 3/8 fuel resistant PVC tubing down the filler neck before you fill up. make sure it is long enough not to disappear down into the tank & short enough not to reach the fuel when the tank is full. It is a good idea to hold onto this tube with you spare hand. Let any fuel in the tube drain out before removing it though & be careful not to spill petrol on yourself. To avoid this bend the tube gently back into the mouth of the fuel filler.

78 VW camper has Gas leak after filling tank, other side of the

I had the same problem as this. There is a pipe that runs from the petrol tank around and up into the air inlet shaft under the spare wheel well. I am not sure exactly what it does I think it has an expansion valve on it. There is a join in this between two tubes that join. This is a simple piece of fuel tube with an internal dimension of say 5mm. If you feel your hand into that air shaft there, locate the fuel tube feel your way along the pipe, you will find the join. Just pull the old one out and put a new piece in. Very simple. really
