Calibrating your Gauges?

[Monte Howard]

I just recently (16 months ago) started a new job at a natural gas compressor station.
Well about six months ago a old timer there was showing me how they use to use these old dead weight tester's to calibrate everything at the plant, gauges ect. Well today I remebered after he showed these old dead weight tester's to me that I wanted to test my gauges on my race car,So I went and got the old timer and he refreshed my memory on using the tester.

I have not tested my gauges yet,But i grabbed three old gauges laying around the shop and they were all off between 2 - 4 PSI.

That got me thinking how many of us have been running lower fuel pressure than we thought,well I know I wasn't because I adjusted my reg. up till it blew by the needle & seat then backed off 1 PSI.

How many of us have been running 24 PSI in our Slicks only to find out we really might be running 28 or 20?

But I thought I would throw this out there to see if anyone calibrates their gauges.

Also anyone have a old dead weight tester laying around, I would like to buy one,Even though I have access to one at work I would like to have one at home also.
