Re: Alfasud Ti Qv 1983 fuel leak
« on: January 12, 2018, 04:45:29 PM »
My Sud is leaking fuel when it is filled up at the service station.
It only happens when the tank is very full and stops when the fuel has dropped a little. While the tank is filling it doesn't occur only when it is getting near full.
The leak is from the area where the fuel hose would enter the tank.
I suspect a upper filler hose has split or perished.
Any ideas? What hose/part number should I look to buy? Any ideas who would have this part?

Hi Herbyj
Find attached a link that provides info on fuel lines ID that are available through your local parts store. If fuel line is found to be perished, I recommend replacement of that section entirely. However, if it is not the fuel line and it is found tank is suspect, then I recommend that this be undertaken by an individual authorized for this type of work (any slip ups here can be catastrophic).

Hi Herby, as seen in the image from Haynes manual for the Sud, there are two rubber components to the filling of the tank.  The upper overflow small diameter rubber hose that flows back to the tank, just near the filler. Or, the larger diameter near right angle bend pipe that goes from lower plastic filler pipe into the tank proper.

Upper hose is generic size hose if it is that (you will need to investigate where leak is exactly). Lower is more problematic but can be obtained NOS.  Try squadra sportiva/shop alfisti in Germany, or Alfa Restoration UK, in Athens, Greece. Two places that list the lower rubber pipes that I know of off the top of my head.

My '85 33 QV has a fuel return rubber hose (?) angling up into the lower section of the plastic tube, just above the large diameter rubber pipe that attaches filler tube to tank. Not sure if your (?) year Sud is same ?

Good luck with the investigation!
