Yeah, It's true, I have a spare K24 lying on my workbench too, there is definitely a hose there, on both of them.

I found a part number for the in-tank filter: 431 201 511 A Another thing you might try (but you're taking a chance with increase engine wear) is to use some 911 treatment, or a quart of gasoline in the fuel tank. If there is wax or ice in the line it might clean it out.

I have been waiting for my shipment of various filters and oil cooler seals for a week now, and the amazing weather that just hit us delayed it further. I hope to have it by this weekend, and before the car is warm in the garage, I'm going to check the state of the fuel when I pull the sender and the filter to see if it's gelling (which I don't see why it would be since I use Howes). I don't know what could be wrong with this car besides that screen because last year I had a major problem with gelling, like anywhere below 15°F it wouldn't do more than idle. So if its actually gelling I'm going to try a new anti-gel and add a bit of gas. An article I read doesn't make me afraid to add a small amount of gas to the diesel, I'm sure its better than the alcohol in the Diesel 911. Thanks Tom for that part number, and thanks libbybapa, I'll check that out, but by now I don't think its anything more than restricted flow.

Regarding the article on adding gas to diesel fuel, what year was it published?

It was posted on a current forum if i recall correctly. basically saying its fine in *small* amounts and even if you filled a diesel with gas it just wouldn't run because of a different flash point or something. Don't think I would ever be this stupid. I have never done this, but wouldn't the small amount of gasoline be better than the nastiness that is Diesel 911? What's harder on the pump?

The Bentley says using small amounts of gasoline is ok in a pinch, get the lowest octane you can. Octane and Cetane work against each other, and you need cetane. [edit]
I use power service anti-gel treatment, and when It gets really cold I use power service and seafoam together. Never had a problem yet.

Ok, so I replaced the fuel filter and it did great for about 100 miles. Then it started acting up again, hesitating and not going over 100 kph or 3000 RPM. The boost gauge keeps fluctuating from these constant hesitations as well. Once I got it home, I replaced the fuel filter (absolutely NO gelling in the filter either), but this time there was no change. It has to be a fuel issue like everyone said, and I have to replace that screen like Tom said, but there is too much fuel in the tank still to do that. (I don't drive too often.) Does anyone have any other Ideas of what this could be in the mean-time while I burn through more of this fuel?
Thanks, and sorry for asking when I still haven't done one of the recommendations.

something is restricting your fuel supply... on the audi's i think its possible to get to the pickup from the trunk maybe? or else you have to drop the tank... it would be a good idea to get a vac gauge on the fuel inlet just to be sure.

An el-cheapo vaccum gauge can be a boat primer bulb, if it squeazes its self then you got a blockage.
No idea how much vaccum it takes to squeaze though but I do know it shouldn't at all.

The reason I mentioned the publication date is because back when diesel was diesel and not LSD or ULSD there was a lot more lubrication in it. You will wear your pump and injectors out much quicker if you mix with gasoline
As for the OP, Do you have compressed air? You could try blowing backwards through the line and seeing if that helps. If you have a check valve this won't work though. Actually if you have a check valve you should bypass it and see what happens.

Here is the problem, I am about 50 miles away from my garage. I am at my University town and have limited tools... I will try to find the screen Tom was talking about after I get to at least a half tank, but until then I don't know, maybe I'll just bring it to a shop that will probably know next to nothing about these.
Can you elaborate on the pickup? I have access to the sender without dropping the tank from my back seat, but like I said, I need to burn off about 5 more gallons before I want to open it up.

Is it possible for you to do a lot of low speed driving an idling to burn off 5 more gallons. If nothing else warming up the fuel in the tank from the return line might dissolve a little wax.
