just posted this in the technical area of the forum but a member suggested to try in this section so here it is:
was wondering what was the function of this valve used on Lotus F1s between 1968 and 1971 and hope some tech expert could help.
I first thought of a fast refuelling fitting but its the position (no cowling opening near) tells not. Collector pot vent valve??
Thanks in advance for any help!
