With the Aux Gas, I do get He flow up to the flow block. I've taken out one of the flow blocks and they seem to be in good shape but even just connecting the He to the Aux Gas connection without the other valves (Hyd and Air) in the block I couldn't get any flow by opening the Aux gas valve and varying the inside needle valve through its range. Then I took out the Aux gas valve and still don't get any gas flow through the flow restrictor alone - the gauge supplying the Aux gas doesn't lose pressure in a several minutes when the gas supply is shut off. It looks like the flow restirctor is plugged. Does this seem possible or reasonable? The only source I could find was priced at $125 for the restrictor - any ideas on a way to fix this without spending the money on a new restrictor?
The other problem I'm having is no flow through the Purge Vent. I've tried with the purge solenoid on and off on the control panel and don't see any flow (although I can hear a "click" when the status is changed). The purge vent flow goes through the chemical traps and I'm wondering if they might be plugged - I bought the GC a couple years ago and the tags on the traps have 1999 and 2002 written on them but I don't know how much the GC was used from early 2000's until I purchased it. Any ideas on troubleshooting this further?
Thanks
