I'm using the Allstar valve from summit. I picked it cause it had the handle I was looking for and fit my dash perfectly.
Its not the valve fitting not sealing. I have a 90* fitting on each side and them an adaptor that the lines fit into. seems the line is not seating with one of the adaptors. I'll post a pictures of my setup when I get home today. Allstar Performance ALL48010 Allstar Performance Brake Shut-Off Valves | Summit Racing
