Refilling and fuel cap

[rfuerst911sc]

I have a 2002 S that I picked up in January of this year. To date every time I go to fill up I have not heard any release of pressure when removing the cap. It does sound like you have a bad sending unit but make sure the chassis ground for the sending unit is good.

Thanks for the reply. So we have similar cars. So maybe I should not expect any release of pressure that's good to know.

I am going to go and look at the sender unit now see if I can spot anything obvious. Will take a pic and report back.

I am hoping it's just a loose connection. I wish.

Looks as though it has had a 'glue repair' previously. Guess that looks like a crack which tells me I need a new fuel sender.

Now need to decide whether to do DIY or take it to the garage

The glue is on there as a tamper marker to show if it's been removed prior. Mine had it on there, too.

I thought something like that after I wrote it. I looked at the pics of others and they had the same. Thanks for that. I will get my hands dirty again and get right inside this time.

Just a thought... If you remove it you may be able to check the sending unit with a simple ohm meter. Most either use that or voltage variance via resistance. A meter would be able to show changes as you operate the float. This has worked for me on many other vehicles with similar issues. Every time, thus far, it's always been a complete replacement of the unit. I've heard some sell the parts separately, but most seem molded together.

So. I have had the car two months. Fuel gauge was on from day one fuel in there orange light on. Stumped and told by garage that needed new sender unit £280 all in. I been delaying it and filling up every other journey

I replaced the fuel cap still no joy but it looked a lot nicer so can't grumble. So today I parked the car on the kerb leaning towards the fuel tank. Left it for a few hours. What do you known. Voila fuel gauge working and needle straight up to 3 quarters. Well happy as was getting to the point of buying a new unit.

So I guess it was a stuck float. Worth checking this before you splash out. One less job to do or pay for
