Oscar Avalle Posted November 22, 2014 Report Posted November 22, 2014 For a while after i land and when it is hot I smell fuel in the cockpit nothing major, but I have not been able to figure out where it comes from. I checked the most obvious places for stains, but nothing. The fuel selector valve is fine, under the carpets nothings... any suggestions???
Marauder Posted November 22, 2014 Report Posted November 22, 2014 You check the fuel sender fittings on the sides? Mine seem to need to be tightened a couple of times a year.
Bob_Belville Posted November 22, 2014 Report Posted November 22, 2014 I think the fuel sender access behind the trim on the side wall below the door and in the same position on the pilot side is most likely. But if you do not smell it when you first open the door before startup I would not suspect that's it since those units are below the "water line". The other possibility if you have the older fuel pressure gauge is that there a leak on the back of the gauge or at the firewall. If that's the culprit it probably only leaks while the engine/fuel pump is running and pressurizing that line which is above the "water line". Look under the panel for signs, maybe while running the boost pump but it might be just a pin hole. When I redid my interior I found the insulation in that area stained with oil, hydraulic, maybe fuel. Glad the new EDM gets oil and fuel lines out of the cabin! 1
HRM Posted November 23, 2014 Report Posted November 23, 2014 My suggestion would be the fuel pressure gauge. Both oil and fuel are "in the cockpit" and although the system was absolutely fine for four decades, after that the envelope is being pushed. I'd recommend getting those lines out of the cockpit, even if it doesn't prove to be the problem. Of course, I am assuming you still have the original analog gauges. I saw a post once where a guy was flying and said that his wife felt something dripping on her leg that turned out to be fuel. Yikes
ryoder Posted November 23, 2014 Report Posted November 23, 2014 I have a fuel smell in the cockpit also and it pisses me off. I am taking it to Edison at wetwingologists in February to get that solved. If it's not the tanks I'll have him fix the tanks plus whatever else it is. 1
flyboy0681 Posted November 23, 2014 Report Posted November 23, 2014 Our fuel sender gasket needed to be replaced, but the smell occurred only in cold weather. 1
carusoam Posted November 23, 2014 Report Posted November 23, 2014 65c, fuel sender gaskets leaked enough to soak the back carpets where the kids sat.... Removed side panels to see lots of dark blue goo... Original gaskets are cork and can stand replacement. Best regards, -a-
Hank Posted November 23, 2014 Report Posted November 23, 2014 Our fuel sender gasket needed to be replaced, but the smell occurred only in cold weather. My tanks leaked very little in summer, but when winter hit WV they really opened up. Four years on my reseal now, and doing well except for some wear on the wing walk that I need to patch up (quarter-sized spot). Cold seems to have that effect.
dcrogers11 Posted November 24, 2014 Report Posted November 24, 2014 I had always smelled old fuel in my 64 C until I pulled the panels for the upholstery upgrading. Both sending units had a slight seep. Simple to fix with new gaskets once you have pulled the side panels. Don
isaacpr7 Posted March 25, 2016 Report Posted March 25, 2016 Does anyone know a part number for the fuel transmitter gasket and screws. Spruce is not very helpful unless a number is provided. Sent from my SM-T330NU using Tapatalk
Raptor05121 Posted March 25, 2016 Report Posted March 25, 2016 Your IA can simply cut some cork out in the same shape. I can't seem to find any online

Give him a ring Monday, most likely he will have them ready to send.

par Posted March 26, 2016 Report Posted March 26, 2016 I have spent a lot of time and money on this issue and I still have fuel smell in the cockpit. It is there when I open the door and its there after I land. Both of my fuel senders were rebuilt a year ago and have new rubber gaskets. I had all the side panels off during the last annual and I did not detect leaks/seeps. At this point, I'm choosing to simply live with it because I have no way to determine where it's coming from.

You might try removing the wing inspection panels that are under the wings, about mid tank, in front of the tank and take a look. It can leak there in front of the tank and then travel towards the cockpit.

Yetti Posted March 26, 2016 Report Posted March 26, 2016 There was an RV builder and his granddaughter taken out by thinking Silicone was good around 100LL
N201MKTurbo Posted March 26, 2016 Report Posted March 26, 2016 I had a heck of a time getting mine to stop leaking. Got everything squeaky clean, new gaskets, new screws, new insulators, still leaked. I finally coated the gasket with tank sealant and that fixed it.

I put 100% silicone to the cork with with my fingers with absolutely no excess. When I need to replace the gasket the cork never sticks.
Sllabrasca Posted April 14, 2016 Report Posted April 14, 2016 I've had fuel smell for as long as I've owned my '64c. I just keep hanging little trees on the rear view mirror! 1
Brandontwalker Posted April 14, 2016 Report Posted April 14, 2016 http://www.aircraftspruce.com/catalog/appages/MC462_021.php Also try your local boat shop... Is this the correct part number for a M20j?
Raptor05121 Posted April 14, 2016 Report Posted April 14, 2016 Fuel pressure line, are they not "wet" coming into the cockpit?
