Fuel tank problem

The tank is behind the dash.

Stunt, there is also a problem with the hoses getting tangled inside the tank near the sending unit. When this happens, the gauge may not read full when the tank is indeed full. I cannot tell from your post if this is your problem or not... This is the problem with my boxster and I am having my mechanic work on it to simply put plastic tie wraps around the hoses to keep them from getting in the way.

My mechanic moonlights out of his home garage, but during the day he works at a dealership. He tells me that people come in with gas gauge problems all the time and it's usually something he fixes with a tie wrap in an hour or so... but the service attendant charges the customer for 4-6 hours of labor to "remove and adjust" something, just because the rate book says that's what should be charged.

I've asked this before at renntech.com. The fuel tank opening is located under the batt. You need to remove the batt and the plate underneath it. You should be able to see it once you've done that. This is only to access the fuel tank opening where the fuel pump is though..... not to remove the entire fuel tank.

Sorry, I don't have that. I just wanted to locate the fuel tank opening and that's what I was told. Left the reat to my mechanics....

I have a 2003 986S purchased in the U.K. If the fuel gets low and 'Check Fuel' warning comes up and I then re-fuel to full, the gauge does not re-set when I drive off, and the 'fuel remaining' figure on the OBC continues to drop until it becomes blank (indicating dangerously low). Sometimes the gauge resets itself to where it should be some time later in the journey, but usually this doesn't happen until the next time I drive the car from cold.

Turning off the ignition and restarting, as recommended by the local OPC does nothing. Otherwise, they have no suggestions. Most likely suspect seems to be tank sender (sticking float?) or signal conditioning software. Could it be cables in tank mentioned already in this forum? Anyone else had this?

Many thanks for any help.
