Euro s running problem sorted. Return line
 

My 83 cis euro car came to me as a non starter. first thing we found was little filter in fuel entry point on the FD was blocked , the car started but wasn't right. Next we found the wur filters had crud in them , cleaned and the car ran better . Next thing finally that sorted the problem and gave me back 250 missing horses was the return line had gummed up and was partially blocked. Blew airline down return line and voila ! Result! Cold and warm pressure now in spec and the car pulls well . All info gathered from you guys so a big thankyou to all the people that put so much effort into making us new 928 owners lives easier.

Cool! Glad it worked out. CIS is great when it's tuned and stays maintained...
