Here it is on Amazon. I don't know of a UK supplier - I would try auto parts stores.

HEET on amazon

thanks, I'll keep trying with the DRY FUEL as HEET doesn't seem to be available in the UK. While its just got 3 - 4 gallons in I will try adding a couple of containers (although it says one per tank) to maximise the affect, leave it to activate for a day or two and then refill the tank thanks again John

If you have water in the fuel - why not use a fuel dryer like HEET.

That has worked for me and is a lot less trouble than draining the tank.

I haven' heard of HEET, who is the manufacturer & where is it available, is it a fuel additive? I tried some DRY FUEL by WYNN'S which I got from HALFORDS which seemed to improve it temporarily but now the tank only has about 3 gallons its playing up again.

If you have a misfire you likely have a fault code or two.

If you have a code reader read out the codes - some auto parts stores will read your codes for free too.

Report back here what your codes are.

Hi,

unfortunately my local parts contacts are not that generous! the best I could find today wanted over £50. Although, using your instructions, tonight, I removed the centre panel exposing the fuel filter & drained out approx 200ml by unclipping the fuel line tank side of the filter. Looking at the petrol in a glass jug, I cound clearly see globules of water resting in the bottom which reinforces my earlier suspicions.

To empty the tank, I tried putting a pipe on the fuel line & turning on the ignitition to activate the fuel pump but I guess it realised there was no resistance & cut out.

Do you know the best/easiest way to empty the tank?

Your time & assistance is greatly appreciated

thanks John

Hi, I recently noticed my 2000 996 C2 cab had developed a missfire, thinking back to its last fuel stop, I remembered finding it very difficult to fill without the pump cutting out. The following week I noticed the petrol station was closed to have new tanks installed. I spoke to a colleague who lives in near the petrol staion who told me that there were rumours that the previous tanks had been contaminated with water.

The missfire was more frequent when the tank was getting empty so I fueled up (at a more reputable source!) but the missfire is still present, it seems worse in traffic but disappears under more heavy load.

Should I persist by refuelling & hence diluting the contamination or do I need to drain and replace the fuel filter as you describe? If so any ideas on the easiest way to drain the tank. Can it be syphoned adjacent the fuel filter

Any help gratefully appreciated. JK

sorry for previous posting, i'm a FORUM virgin!

Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers.

Parts you will need:

1 996 110 253 01 Fuel Filter - for 2WD cars

or

1 996 110 253 52 Fuel Filter - for 4WD cars

Tools you will need:

Tire ramps or jack (and jack stands)

Various screwdrivers to remove underbody cover

The fuel filter is located in the tunnel area facing the center unit above the coolant pipes (up to and including MY01). MY02 and newer cars have the fuel filter incorporated in the fuel pump - and usually does not need to be changed. This DIY is for MY01 and older cars.

1. Remove cover for rear and center underbody. (photo courtesy Tool Pants)
   
   
2. Pull off ground cable on filter. Then release the rapid-action couplings by pressing on the grey surfaces and remove the fuel lines. Collect emerging fuel.
   
3. Loosen the large hose clamp on the filter and remove the filter element.
   
   
4. Re-install a new filter element and tighten the hose clamp.
   
5. Join the rapid-action couplings of the fuel lines. The plug connections must engage audibly. Then push the ground cable onto the filter element.
   
6. Replace the cover for the rear and center underbody.
