(No more) Soot and dirty oil building up around glowe plug

The reason that hex head screws can't be used with a Bosch pump is that the heads are located in a recess, whereas on the LUK pump it's just a flat surface.

Its only hex head bolts listed in the audi7zap.I had the understanding Bosch was the manufacturer for some pumps on some of the engines.
Could I reuse the allen head bolts from the Luk on the Bosch, do you think.Would they be the correct size?

Yes, they should be fine.

Another question; I am a bit confused what seal to use when LUK goes out, and Bosch goes in.I had the understanding that the metal seal ( 038 145 215), and not the light green rubber seals ( 038 198 293 A) is a fit with Bosch?

In audi Zap it look like something is different after WIN 03, and I do not know if I understand it right.Only for this, not for that etc.

Yes, I think that's correct. The pumps aren't supplied with a gasket, which is a bit silly!

Hopefully the problem is solved, installed a new Bosch F009 D02 799 with seal from Audi today.No need for a spacer to clear ASV valve, since it is a lhd car.The old pump had a spoonfull of sludge inside, and the spigot had 0,3 mm of play.
The Bosch' spigot has a more solid construction.
Thanks LUK, for your rounds.And thanks to Audifan, RAB, a.o, for the support.

Edit:The new pump gives more support to the brakes, the good old feeling of direct response with a touch from the toe is back!
