Help! 1969 oil pressure gauge issue

[royvaldes]

I have a base 1969 with a 350. Oil pressure gauge was working fine, but the oil pressure line to it failed . I replaced it and when I bleed it I have great pressure at the inlet to the line and it only drips out of it. Verified no kinks in line. Currently have 2 lines in the car. Barely reads any pressure at gauge with either. One reads more than the other. help.

There's no need to bleed the lines. No idea why your not getting pressure at the gauge end. Are you using the correct replacement line or something from a hardware store?

As you know that is a direct pressure line to the gauge. The fittings are a little different so always use a line kit from a corvette vendor to get the correct ferrules. So if you tap into the block with any mechanical psi gauge to get the reading, the you find the dash gauge doesn't show the same pressure, if at all, then I would look at the back of the gauge. On my 69 there were some foam strips to isolate the gauge and over time one loosened up and jammed in the gauge. Once I corrected that the gauge worked fine.

using both a standard oil pressure line (generic) and the metal factory unit from a vette vendor. similar results
