Just a quick question before I dive in and get my hands dirty, as it were. I need to completely drain the 22 year old fuel from Ulrich the P6's tank and lines - had a look in the factory manual but it's a little short on detail - are the connections to the tank accessible from under the car, or are they best accessed from the boot compartment? Also, has anyone fitted an inline fuel filter to one of these cars? Is it necessary to change the hard plastic fuel pipe to a rubber one to do this? Thanks.
