how does the fuel tank breath


Recommended Posts

The injection tank breather goes via a non-return valve to the carbon fumes canister in the engine bay that is part of the evaporative loss system.

Pre-SVA cars who take this system out have to undertake a modification that keeps the valve but routes the tube at the side of the tank in a zig-zag so you don't get major turn-over spillage

Graham, as you say, can't see any way the cap (flush) breathes, but there is a small hole in the sender unit on top of the tank, there are signs of fuel escaping around this area, but could be a bad seal, still *confused*
