There seems to be at least 3 all with different part no that say they will fit my car 042 052 029 bit confused . Am i right in thinking that this acts like a fuel pressure regulator .

The number I gave earlier came from the Bosch catalogue.

I dare say other parts will fit - how the car will run with them fitted is another matter.

It does a similar job to an fpr - it smooths the fuel flow to prevent surges damaging the metering head / injectors

Coupe quattro with the KV used 0438 170 061 after 1986. Audi number is 443 133 441

Makes me wonder what's the pump in question. When I was interesting about new fuel pump some years ago, I got replies that new Bosch or Pierburg [OEM] was amount of money, equivalent to some 120 pounds.

I doubt there's anything to rebuild - usually the failure is fuel leak caused by corrosion... :D

It's basically spring loaded membrane which stores small amount of fuel under pressure and releases when there is sudden drop in pressure in system. According to some manuals, K-jet systems has twice as much pressure accumulator volume as KE-jet systems.

There are ones available for around £60 - I never said it was Bosch or Pierburg.
