Untighten gas caps

 

gas cap are off

 

If the petcock has a vacuum line attached to it, you need to supply a vacuum to that line in order for the petcock to flow.

Otherwise, use a siphon hose.

 

Siphon hose is the easiest and cleanest way to drain it.

 

got r done with a siphen hose. Thanks for the input. I guess iam just use to an old style of petcock

 

Vacuum activated valve back side of the petcock. You have to pull a vacuum on it.

 

There is a vacuum hose on the BACK side of your petcock. You will have to pull the hose off and connect a hose and vacuum gun to it.

 

I had a petcock once. My ex ended up with it in the divorce.
