OK I checked my Truck at my Mechanic's yesterday.
It DOES have an EEC System.
It does not have a "Threaded Neck" nor a "Deep Cam".
In fact, the cap that is on there now, closely resembles,
a radiator Cap (it isn't though).
The cap that is currently on there is NOT a Vented Cap.
So I'm inclined to just order a Chrome Locking Cap from Classic Industries for $6.95 and see if it works.
It is more about aesthetics than to protect someone from stealing my gas or putting some CRAP INTO my Tank.
In the 20 seconds it takes a Thief to go get a Screwdriver, he may think twice and go for the Gas in the Vehicle that is parked a couple lengths down the street.
Now getting back on topic, if I were to put a Non Vented Gas Cap on an EEC system, what is the worse that could happen?
Would the Truck stop running because there was now a non vented cap on it, causing (lets say) the Gas Tank to collapse inwards/suction?
I'm sure the cap that's on it now is NOT vented, and I've been driving it for 2 weeks with no adverse effects.
