hilljack Member Registered: 07/05/13 Posts: 296 Loc: New Mexico, USA	Cool, thanks. Is it a needed part or can the fuel system run ok without it? Plan on making some changes and that may not be used, if it is not needed. _________________________ 2004 Crown Victoria Sport LX Factory Rear Air Ride/HD KYB Shocks JMod, 3L27, MagnaFlow mufflers 04 CVPI Air Box/Zip Tube, 70 mm Truck TB, AED SC @ 6PSI 140,000 miles
