A MPG question.

[Syncro G]

I only ever manage to really brim the tank on every third fill or so.

Yes it does seem to have that cycle, which I just can't figure an explenation for. Is it actully the fuel going in or the air comming out that does it then? Anyone whos had the tank out and breather lines checked recently noticed an improvment?

I brim my tank every time. It can take a few minutes though, longer on a wet day! Ive renewed all the pipes on the tank
