Check and tighten fuel filler neck up near the cap. Check and tighten bleed tube near cap. Don't fill to full capacity as the fuel will get to the canister and cause you more problems. Fill to first click of the pump hose .

SOURCE: Audi A4 1998 water leakage from centre of the underside of the car

OK more information is needed on the leak.
EXACTLY where do you see it? Inside or out side? What color is it? Dose it have an smell to it?

Now on the light, What light or symbol is lit, get a photo if needed?

A leak in the center of an Audi is generally the AC condensation drain so this is why I need more information. The 2 may be not related.

SOURCE: Fuel splash during fill-up

pull out the gas nozzle a little and then try again...because some tanks are just made wrong and if you move the nozzle back out of the tank and try to pump a little slower that might help you...hope this will help you...good luck..

SOURCE: gas tank?

It sounds odd that both cars are experiencing the same problem. This usually indicates a problem with the gas tank not venting properly.

SOURCE: my low fuel light came on and the gauge read so but upon filling

Sounds like your fuel sending unit may be bad, or you have a hell of a leak. Should still be under warranty.

Have my car on 3/4 full want to top it up but fuel gauge still showing 3/4 full


Fuel gauge is inaccurate. Just keep filling tank till it takes no more. And knowing the gas mileage you get on the car and fuel tank capacity, set the odometer and when you calculate that you are getting close to the bottom, get some gas.

Where is the overflow vapor senar located


If this is related to the fuel filling, evaporative canister issue, maybe the following will help. Most of the components for the fuel tank are located near the tank itself, with some near the front of the tank and the evaporative canister components behind the driver side rear wheel inside a splash cover.

The biggest problem people complain about is not being able to fill the tank without the pump stopping if the tank is filled at a higher rate than a trickle. This issue is caused by trying to overfill the tank after the fill nozzle has clicked off causing fuel to damage the evaporative charcoal canister clogging it and causing the blow back to the filler neck and fill nozzle, simulating a full tank shut-off of the filling process. This is not exclusive of Hyundai, and gas pumps usually warn of overfilling the fuel tank because of this known result. This evap containment mechanism was developed for the cars to replace the vapor collecting mechanism that gas stations used to use partly for the fill nozzle and collection dangers, now all that vapor is collected and safely burned when the engine is running. The evap canister can be expensive to replace, in the neighborhood of $150 from the dealer, and it's not recommended to try and bypass the system or you can create more issues than you solve.

If this isn't related to your issue, sorry, maybe you can post more info on what the issue is and how you need help.

Engine acceleration problem when fuel tank is half full


You need a new fuel pump. Get the pressure on it checked,. I bet it is borderline. With the tank full there is a little extra weight pressure, when half full that advantage is lost.

No fuel guage readings,cant use front fuel tank vehicle stalls out,fuel coming out of front fuel tank cap when running,1988 ford e150


im thinking that this has dual tanks and one of the selonoids that switch the tanks have failed, Its the fuel coming out the cap that is tough. does it flow out the cap like its over full or is it just a couple splash drops like rain drop? does the other fuel tank read the same fill level while this is happening?? Cause the only way the front fuel tank can get full is if the fuel is being pumped into it by means of the fuel in the other tank. Now im not sure if they run return lines on that but if they did and the return line is near the cap i could understand the couple splash drops. Vehicle stalls on the front tank because the selonoid that opens and closes allowing fuel to be picked up to the motor is bad or the electrical switch or wiring is bad. selonoids are located under van close to the front of tank.

We just got a 1988 Porsche and filled with 1/2 tank, there was what seemed like overflow happening - Any idea what may be the problem.


fuel tank vent could be blocked by mud/pebbles etc, not letting the gas fumes escape while your adding fuel making it overflow, check underneath the car near the fuel tank .. something to start with..
