Hi guys,

I tried a search on this and did not see any immediate responses.

Took the Disco on a long run today to see how the fuel milage is since fitting a recon dizzy vacuum advance. It did 14l per 100km travelling at 118kph with aircon on (freeway driving).

The problem I encountered is when the engine was shut down, a whistling noise came from the fuel cap and the pressure behind the cap was really bad!
Double that of our AUIII Ford.

Is this normal?

Cheers,
Ron
