ranchhopper Posted November 29, 2014 Share Posted November 29, 2014 This is some kind of air pressure sending unit I cant find it in the parts book when the truck is aired up it leaks lots of air out of the lower part where the wire connector is. It is located in the cab on the firewall just behind the clutch pedal it really leaks a lot of air has anyone tried to fix one of these?

ranchhopper Posted November 29, 2014 Author Share Posted November 29, 2014 I thought that's what it was but I wanted to sound like I knew what I was talking about when I called for one.
