I'm trying to clean the fuel tank of my 1993 Audi 80, (renamed as Audi 90 in the U.S.).
I took out the pump, the pump holder cup with the sieve, fuel gauge ...but how do I get the sediment bowl out?
First of all, does it come out? Does it come apart somehow, because it's bigger than the hole/opening on the fuel tank?
What about the little switch-thing on its right side? What is it for?
Thank you.

had engine rebuilt it turns but wont start their is fuel and spark change the crank senso checked the rpm sensor

need to know when the belt tensioner is located on the engin replacing altenator and there is not a diagram to be found.

Car was running little hot, then ran hot hot for a few minutes and engine stopped, started one more time, enough to drive to a safe spot, still hot, stopped and won't start. Sounds weird when tries to start. Is this a timing problem or engine replacement?

Car was driving with no apparent problem. Then it just suddenly wouldn't start. The igition, starter and battery seem to be okay. It seems to want to ignite but then just rolls over and over with out starting.

I have a '93 model 90, six cyl. that wouldn't start. Replaced the ignition control module, plugs and plug wires. Now it seems to start when cold, but not hot. Does this sound like crank sensor? If so, can anyone tell me where to find it, and if I can test it?
