I have recently bought a Fuelab 525 series fuel pressure regulator,and wondered if anyone could tell me or with pictures,how to plumb it in to standard fuel system,i have the fuel rail adaptor,to replace the existing fpr.The car is an MY98 UK turbo 2000 with standard fuel rails,not parrallel.
Any help would be appreciated.

 

Put the adaptor inplace of the OEM one (near the turbo) run a pipe from the adaptor to the reg then another pipe from the reg to the return line which is one of the three at the top of the bulkhead at the passenger side.

 

You have two fuel lines and a purge line which make up the three daz has described.The return is one of the two larger pipes,not the one connected to the fuel filter.

 

Thanks guys.
