Hey Steve – thank you, ours is not on that list (close – it is SN 7790356) so I agree that that may be the place to look as well. I’ll let you know what we find.

You can pull the fuel tanks and check for the integrity of the flexible tubing between the tank and the airframe. Piper suggests that that be done every 8 years.
AD 79-22-02 applies to the following Piper singles:
79-22-02 PIPER AIRCRAFT CORPORATION: Amendment 39-3595. Applies to Model PA-28-161, serial numbers 28-7816024 through 28-7916475; Model PA-28-181, serial numbers 28-7890023 through 28-7990493, Model PA-28-201T, serial numbers 28-7921001 through 28-7921068; Model PA-28R-201, serial numbers 28R-7737135 through 28R-7837317; Model PA-28RT-201, serial numbers 28R-7918001 through 28R-7918172; Model PA-28R-201T, serial numbers 28R-7703309 through 28R-7803373; Model PA-28RT-201T, serial numbers 28R-7931001 through 28R-7931222; Model PA-28-235, serial numbers 28-7710079 through 28-7710089; and Model PA-28-236, serial numbers 28-7911001 through 28-7911204 airplanes certificated in all categories.
The AD says it’s to: “To prevent possible fuel leakage and potential fire hazard” To comply the fuel tanks have to be removed and new rubber hoses installed. It calls for the installation of service kit 763-934V. You can buy one but by viewing photos of one for sale on ebay: https://www.ebay.com/itm/264897159867, it’s pretty obvious that the kit is some new hoses.
The Piper Service bulletin mentioned in the AD, service bulletin 646 isn’t worth much.
I think that’s where I’d look.
Please let me know what you find.
Steve

Hi everyone,

PA28-181 – 1977 Archer II – When we fuel up (even to the tabs) we will most days smell fuel in the cabin while taxiing and then for about the first 2 or 3 minutes and then it goes away. We cannot find any leak that is visible. There is no obvious smell near the primer or the valve R/L switch. From an article by Steve Ellis in January of 2011 we suspect that it may be deterioration of the fuel vent lines – we detect no smell near the gascolator though I have to admit that we have not shut down to pop the cowl and check that carefully – now that I think of it we will try that. Any ideas about smart things to troubleshoot this issue are appreciated.
