any idea why this is happening how does the evaporative system work?

New one to me.
given the lines and tank are external....i would be first inspecting the flexible fuel lines in the engine bay.

We have fuel vapour in EL wagon at times. doesn't need to be hot either.

Haven't found cause yet but boss is not happy about it.

Describe the symptoms . It might be something quite simple .

hillster

well if i drive the car. then park it and come back and sit in it all i can smell is fuel not from outside the car but sitting in it.

When It happens, undo you fuel scewcap. Does air rush out or in ?
If out then your vacuum/fuel vapour system is to blame, happens every couple of years in mine.

This burping will fix it temporarily, I honestly cannot remember what the permanant fix was :-(

New cap needed; valve in cap has failed.

Hillster,
is yours a sedan/wagon/ute. You also do not specify model.

Fuel smell in a wagon is quite plausible. Likely culprit is the filler neck tube is not tight..

There should be pressure in the tank...it is a PRESSURE system afterall. Go play with crumpledores or toyota's you will get the same response from the tank upon opening.

Cheers
