I tried just sucking on them (keep it clean!)with a piece of vaccume tube and they moved a little and I heard no leaks is that good enough? I will have to try the vaccume port next time I start the cars up, thanks for the tip.

They are usually pretty reliable but I dont like the idea of a possible constant vac leak messing up my air/fuel ratio in the eng & also I want to KNOW that everything is right.

I do not assume anything. True, Probably would come in handy for all types of things I would assume, especially with the vaccume operated nightmare on the Charger. would this be a good "starter kit"? http://www.tooltopia.com/index.asp?PageA...;utm_medium=PPC Last edited by challenger70; 01/13/09 01:21 AM.

The one in my pic I got at sears & though I am no longer a fan of sears declining quality I have had this one for quite awhile(& it is sturdy) & dont remember what I paid for it & actually haven't used it much but when I have had a need for it it has come in real handy. I'm thinking that in a prior thread on brake bleeding that people who had Mityvacs were happy with them. live every 24 hour block of time like it's your last day on earth

This would be the same effect as a vacuum pump & it'd be free & I'm thinking that those A/C pods get full eng vacuum. No need to buy a Mityvac if you didn't have to. live every 24 hour block of time like it's your last day on earth

Gotha, it's not too much of an outlay, and it looks like it would come in handy for brake bleeding and other stuff, I will do a little more research and maybe pick up a mityvac. Thanks for the help.
