Yes, I did replace this 3/8 inch rubber hose. This hose attaches to the PCV valve and another hard plasic hose which goes somewhere near the firewall. I went to the stealership thinking it was a special hose since it had a slight bend, but the parts guy said it wasn't a Ford part. I think it was damaged/cracked by a "mechanic" when I had my precats replaced in March 2002 ( don't ever let Midas work on your car ... long story). During the intake rebuild (Xmas 2003) I noticed a 19mm socket resting on the ATX. I think it fell down there during the precat repairs and the hose was damaged when somebody tried retrieving the socket. My CEL light came on around August 2002 with P0171 DTC.
I'll keep my fingers crossed for ya.
