If thats the same banjo as the one listed in the 044 sticky thread i should have one here..

I think (without checking part numbers) the basket is the same in the S2/S4/S6, certainly takes the same pump. I had a peek inside a few fuel tanks of regular 10v 5cyl Audi 100's in the scrap yard and they all had the larger pump basket as the 10v coupes, which is the basket you need for an 044 pump. Never did think to take one mind you.

definitely not in S2/S4/S6, you will find them (baskets 895 201 779 H) in A100 C4 with AAD (2.0) and AAR (2.3) engines; A200 with MC, 1B, 2B; A80/90/Coupe with NG, 3A, DZ, KV, AAD, 6A, ACE, ABT, ABM, NM, 7A

strainer 895 201 531 A in the same A100 C4 with AAD (2.0) and AAR (2.3) engines C3 with PH and 4B with 4cyl; KU, MC, NF with 5cyl; A200 with MC, 1B, 2B; A80/90/Coupe with NG,6A,ACE,3A,DZ,KV,AAD

so these parts are not something special and unique from V8

Has anyone fitted a brushless Bugatti veyron pump inside of a urS or b3/b4 fuel tank? I was going to run a twin bosch 044 surge tank setup
but supposedly that veyron pump can support 800awhp on E85.

Ah come on! ………… we're talking the real world here for mere mortals.

I've ordered the parts I think I need from the dealer, and so will hopefully be able to post on how I got on, and that it worked out fine. We'll see………..

Are you going to run E85?
If so, steer well clear of the 044. Mine lasted 9000 miles. Bosch rates them for max 500 hours on E85, mine lasted approx 170hrs which is pathetic.
I did some research on the Pierburg pump that is referred to as the Veyron pump, but I went for the Walbro GST450 that is fully E85 approved.
Will post a how to on how to fit it, as it required some special parts in order to fit it in the RS2.

Audi 200 20V (3B engine) has also the right basket for 044 pump...

[orignalS60]

Yes two maps E85 and unfortunately 91 octane + meth.
I used to be able to get 93 octane amongst other fuels
at the pump in Florida.

The parts I ordered were fine. But the inner section of the basket needs to be cut down to allow the 044 pump to sit down low enough in the basket / tank to ensure that the pump can pick up 'all' of the available petrol when the petrol level is low in the tank.

In order to facilitate the 'easy' cutting of the hard plastic, it may not be obvious, but the inner top section of the plastic basket can be separated to allow it to be put / held in a vice to hold it for cutting the top off this section of the plastic basket, to allow the pump to sit lower in the basket / tank. It also cuts off and gets rid of the small little gauze at the top of the little round breather that gets in the way of the 044 pump being put into the basket from the top.

In order to make this separation of the sections of the basket, when examined one should see that with the insertion of approx. five smallish flat head screwdrivers the inner section of the basket can be gently 'levered' / 'pulled' out. You may or may not need an assistant.

Not sure if this make sense or can be understood, but it is well worth getting to grips with it if you are putting in a 044 pump for the first time.

The other thing you will need is a head tourch with LED 'bulbs' to allow you to see into the tank. Also remember the pump is not directly beneath the access hole.

Also for added fun, on C4 & B4 saloons, you obviously cannot access the tanks access hole without having contort oneself repeatedly to get into and out of the boot, as well as when you're 'lying/sitting' in the boot. You'll never have all the tools with you in the boot to do the job in one go. A upside down milk crate outside the boot makes the step down less stretching for older members such as myself. It is easier for Avants and Coupes as you can put down / take out the rear seat.

Take out the spare wheel and everything in the boot to help yourself. Have plenty of kitchen roll to hand.

Also remember to decide which orientation you want for the new pump, as the old pump has the pipe exiting from the top, the new one has the exit nozzle comes out at a right angle and so therefore you need to ensure that the direction it points doesn't foul the operation of the fuel gauge float / rubber pipes & electrical wires, otherwise you will be having to 're-enter' the tank to fix it and while also making sure the tank is nearly empty. Measure twice and cut once. It is a pita of a job and you don't want to have to revisit it.

Also do the job in a pre-emptive manner rather than when the pump fails. It may be a pain to do it this way, but it is an even bigger pain to have to do it in an emergency manner, i.e. no pump or parts to hand when the original one fails. It never fails at a good time. Dave is right, they do not last forever.

My car no longer pinks, and now pulls / revs as it should, i.e. like a machine, rather than someone with chesty cold.

There is a high pitched whine from outside the car, others will probably never notice it. Whining inside the car may be due to the way the pipes from the pump to the tank lid are positioned / stuffed back into the tank as you tire of the job, so take you time to ensure the pipes sit comfortably / as best as you can get them to fit.

Hope some of this long winded waffle helps others who have an old / original fuel pump in an ABY/ADU and ANN car.

Good point on pre-emptive replacement of the pump. I will be doing that on the 2005 A4 as soon as the parts show up from Germany, as the car now has approx. 130K miles on the clock.
On the 80 Avant, it failed at 125K miles, at a very invonvenient time and place, of course.

The original RS2 pump was fine when I replaced it with a 044 at 90.000 miles, then the 044 lasted 9000 miles before it was stone dead..

I saw a writeup somewhere where the guy added a cut down fitting at the bottom of the 044 in order to have it extend all the way to the bottom of the basket. Pretty clever.

Note: The gauze on top is a filter, so it would be a god idea to use a soldering iron in order to seal it in place after cutting that opening, otherwise, the pump will suck in a small amount of unfiltered fuel. However, being on top rather than the bottom, it is likely not nearly as critical as having a functioning strainer at the bottom
