Clutch Hydraulic Line

[73737373]

1991 Silverado 1/2 ton. 4.3. NV3500 5 speed manual. 325K miles.

Have blown 2 x Dorman (Auto Zone) clutch lines (at the hose/metal tube joint) trying to bleed this system. For anyone who's never bled this system before, it takes a while, which is frustrating enough, but to have 2 "defective" hydraulic lines is even more frustrating, not to mention brake fluid sprayed all over the firewall and hood insulation. Nonetheless, once the system finally builds pressure, the line will burst at the joint where the metal is joined to the rubber hose part.

1. I can't think of anything I've installed improperly; master cylinder and the slave cylinder are pretty easy, bolt on/off. Its a pretty simple operation.

2. I've searched for AC/Delco part, but am not able to locate one. Any recommendations for a non Auto Zone part? Auto Zone has been great about exchange/refund and even gave me a quart of brake fluid.

Kind of at wit's end.....
