Default EVAP

As I stated in my other post, I have just replaced the pump assembly. And on my 98 Cherokee that means dropping the fuel tank.

Managed to get everything back together this morning and all seems fine.

However, I noticed that the EVAP solenoid keeps cycling. It doesn't when the engine is cold (which is the way it's supposed to be as far as I can tell).

But with the engine warmed up it keeps cycling about once every second.
I've been going trough the various workshop manual, but I can't really figure out if that's normal, or at what rate it should be doing this.

That's normal. It's removing the fuel vapors from the EVAP sytem.
