I have just got my 73 2.0 back and running, rebuilt the carbs, new distribtor, points, wirers, ect., but just the other day while trying to tune the carbs I noticed air bubbles cumming up through the clear fuel line that comes through the body of the car and the are bubble are collecting to for one big bubble in the hose just before the carb., any ideas.
IME - they all do that...
if it's objectionable, find an opaque fiilter ...
I've had carbs for years and haven't seen bubbles.
I have clear filter mounted on the side by the battery just after the fuel line comes up from below the engine shelf.
My fuel pump is up front directly under the tank.
Where is your pump mounted?
When filling the tank, the fuel is aerated. If your tank and lines have been empty for a period of time, those bubbles can adhere to lines (cohesive) and get washed off after a time of flow. Fill a glass of water and watch.
Otherwise you could be sucking some air on the suction side of your pump at the pump fitting, but......,
I get air bubbles stuck to my beer glass when I pour a Guiness. Hmm but that is a good thing. Same principle????? Aerated fuel when filling. I'll buy that.
Toothsheaf Stout - bigger bottle - more bang for the buck
