I've had an audi 80, yr 91for a bit now and somewhat recently it sarted to have a power loss during deeper acceleration. It first was not very noticable but progressivly got worse on a daily basis to the point now where it won't start. I believe it to be a fuel pump/filter issue based on what I've read and how it correlates, anddidn't know if anyone with more experience knew if I should start with the fuel filter or change both at the same time. Both are exposed near the back right tire and I'd like to avoid a trip to the tech if getting under the carand doing it up all nice'n'stuffmyself doesn't require to much GENIUS. Any guidance or opinion would be nice.

 

change the filter first
