Fuel Vapor Orphan Line
hogswan replied to 496fe's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Going off memory here having been through my entire evap system last Spring, but I believe the circled end goes into the opening under fuel filler door. With door open, the hose end would go into a hole behind the door (opposite side of open door from filler tube). Has no home without fender and filler compartment being present. Best of luck. -
Problem fueling after replacing AOS
hogswan replied to hogswan's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Thanks for suggestions but had already tried all those options to no avail. Finally tracked issued down to mice having eaten through the wiring for ORVR valve on top of fuel tank. This must have happened while I was replacing the AOS at the opposite end of car. Car was fueling fine prior to this project. I guess we can say the AOS replacement was temporally but not technically related to the EVAP/fueling issue. On C4s, and I suspect C4Ss and Turbos, this wiring and valve is only accessible by dropping fuel tank from car which requires dropping front drive/differential and much of front suspension. Nutty amount of work (done by shop) for a mouse/rodent? Bright side is that I'm now very familiar with EVAP system for AWD 996s!? Thanks. -
2001 C4, Manual, Coupe Preemptively replaced AOS last weekend in preparation of track season. Since then, I have not been able to fill-up with gas. Can get in about 0.3 gal before pump handle automatically shuts off and I start seeing gas at top of filler tube neck. Gas gauge reads empty which is in accordance with mileage since last fill-up. I have not CELs, no noticeable vacuum noises, and no running issues. I have checked the fuses (E6) and swapped the fuel filler vent /bleeder valve with another used one that I have no reason to believe was not previously working (no new ones in the US right now). Next step is to check all the related vent lines for obstructions. However, this seem too much of a coincidence with my work on the AOS. Any thoughts as to something in the engine bay that I may have goofed up that would be causing the fueling/tank venting problem? Thanks in advance for your help.
