Hurst Line Lock problems.

[Eman]

I've had one on my car for over 20 years. only problem I ever had was operator installer error. I made the mistake of using teflon tape on the fitting threads. A piece of tape broke off and was on the needle valve. I disassembled and rebuilt it, no problem. They are simple and easy to rebuild.
The Hurst Line Lock is designed so that you can activate it and then pump more pressure as it is designed for that. Some don't work that way like the Moroso I had where you had to stand on the pedal then activate it.
