I am selfishly claiming to be the most desperate alfa owner in US. Been working on this prob for over a year. Have a strong fuel odor in trunk , and sometimes it migrates to the cab, here's what Ive done (have taken some advice on this forum, and has helped some, but not there yet!) Have removed the gas tank, drained and dried it, pressurized it and with soap suds, found a pin hole at top where the 2 little elbows orfices are soldered to tank, near the main fuel fill tube. A specialty shop repaired the pin hole. Then while the tank was out, I pressurized it again to check for more leaks with soap, especially around the middle of the tank where the two seams are soldered together . Aparrently, no leaks. OK. Put it in the car. Reseal all around with finger caulk, tedious job, reconnect tubes, tightenclamps, add gas, drive it, and still have about havf of the gas odor occuring! Have removed the hose from the black plastic vapor collection box, and added pressure, and resprayed with soap on hoses, fuel filler hose connections, etc. CANT FIND THE LEAK. This may be a clue: when I place my entire head in trunk very close to fuel filler hose area, and smell around, odor seems to be concentrated close to that area of trunk, not near the blk plstc vapor collection box. Again, if I presurize tank and spray, NO Bubbles apear. Am I the only one with such a problem? Thank you for trying to send me advice!!

Thanks for your time, redspiderveloce, alfa88grad, farace, and tifosi. I should have mentioned I have an 87 spider veloce. From your responses,I think i'm on to something.....What if I replace the charcoal in canister???? Anyone tried this? where can I get some (the right kind) of activated charcoal? Is it replaceable?This may not help, as I get odor buildup after a short trip, and in theory, the canister is for vapor buildup AFTER engine use (or is it?). PS Farace, I'm orig from Hartford! Currently in Fl. Where are you?

OK, esc2064, Ill look at the cap, but I think the rubber gasket is good, since when I pressurized the tank , the pressure held until I unscrewed the cap and Wushhhhhhhhhhhhh. So Cap may not be the prob, but thanks.
Tifosi, I lived in Plattsburgh from 81-88. where are you? And, DB9. I'm in Tpa-St. Pete area. I guess WE have AC working in our car!

Tifosi, I heard of Watertown. Probably as cold as plattsburgh in winter.Keep the alfa free of salty snow! Thanks for response! Joe
Also, to TIPO101, (Jonathan), Thanks for the info on stuck check valve. I'll look for your post for the bulletin. I'm not for absolutely sure it is stuck, but I guess the bulletin will help v much. Thanks again for your invaluable help.

Kenny,
Thanks for advice on canister. Do you believe that after 18 yrs a canister needs to be re built with new charcoal? Did you notice the difference?

Tipo101,
thanks for posting this info. Thanks Tifosi for your shared info. I'll study this drawing the next few days(I do things slowly, but thoroughly), and see if it will be a fix for my situation. I will keep you advised of my success or not. Thanks!
Joe
