Locking Gas Cap?
Yahoo Message Number: 24691
I searched the archives and don't see anything about the gas cap so maybe I am the only one who wants a locking gas cap? What I want to know is whether the tether on the gas cap is also a sensor that will cause the check engine light to come on if a different gas cap is installed? (which does not attach to the tether) I love this site with all the smarties on it!

Mari, We purchased our locking gas cap at a Ford dealer while traveling in Carlsbad NM last winter. It even says Ford on the key hole cover. As I remember, it was not inexpensive but it fit properly and locked perfectly. A locking gas cap was recommended in the literature for Mexico travel since a Pemex attendant could begin pumping gasoline into your tank before you got out of your rig. This doesn't ever happen really because the attendant needs to know how much fuel you want and which grade you need before pumping. The new digital Pemex pumps really prevent fraud anyway. We use the Magna grade down there.
Another Gringo fear dispelled.

Mari,

Nope, the tether is not that smart.  To bad too, it would be a good reminder if you left the cap off.  The light might eventually come on if you left the cap off, but it wouldn't be because of the tether.  So, go ahead and install a locking cap.

THanks Victor,  so should I just cut the tether off? It is not connected to anything on the other end? Mari

Mari, Before you cut the unbilical and toss your gas cap, you may want to talk to your Ford dealer and ask if it will compromise the fuel emission system. Also you will want to determine if there is a locking cap available that is compatible as to fit and proper pressure relief characteristics.  Tom.

Thanks for your advice Tom, I agree, better to be on the safe side, I did purchase one from Auto Zone that is compatible for the Ford E450 and fits. I am going to save the old one just in case. Checked the tether and it is not hooked up to anything, just knotted on the end.
Now I would like a locking fresh water tank cap............. maybe camping world? Mari

That sounds like a great idea, but I can't seem to get it off the old cap without cutting it, (I didn' do that yet) and the top of the new cap doesn't have a place for it either.........
