twin tank venting

Post by 360gts »

Trying to find the thread on this topic...not having much luck.
Does anyone have information on the service bulletin that covers this???
Looking at my cars (my 69, and both 67's have it installed at the factory)...my 65 looked like it was dealer installed....

That looks like dealer installed (same as my 65)...does the service bulletin say that this was to be done on ALL cars with twin tanks?
My other cars have different tabs for the pipe on the RH side.

Hi there - I have a Serck right hand tank and have vented the tanks in the standard way - i.e the pipe vents through the boot floor on the same side as the tank - what is the benefit of crossing over the vent pipes?

Many thanks

Mark

It was to help prevent siphoning the fuel off if the car was parked on a tilt if I remember correctly?

I thought I recognised that picture Swifty :)

Dermott, that wasn't dealer installed but I think I did a reasonable job of it ;)

You sure did...it looks exactly like my 65 which was dealer installed..a grand job you did.
So, back to my original question....did the service bulletin cover ALL S models retrofitting all the way back to 970/1070s with the optional RH tank?.....I know why it was done etc...

Excellent this is just what I was looking for!

Do we know what clips/nuts were used at point A?

Any images of factory installation?
