These have the advantage of still functioning in case of the discharge of a EMF pulse type of weapon nearby. You never know!

1. Website SAYS anything past 1996 - if your vehicle is close to this age check carefully that your vehicle is OBDII. My truck didn't get OBDII until 1998. Prior to that your manual should say OBD or OBDI.
2. Milo - spot on about the vacuum gauges, I actually went looking in JCWhitney recently for "trip calculators, fuel computers, etc." to find that almost all the '70s devices that ran off vacuum were no longer sold.
3. Be advised vacuum only works on gasoline engines.
4. Milo - funny you mention EMP pulse; for different reasons I actually crawled under my hood and installed a mechanical fuel actuator in place of the .98c relay that allows fuel into my diesel. Stupid failure point designed to make diesels "user friendly". And after examination, one of the few electrical parts that could keep my diesel on the side of the road.
And how many thieves would anticipate hitting the starter and then pushing in the fuel handle? A serious question here in Phoenix.
