Can anyone tell me if there is a difference between wet and dry pressure gauges.
I tripped at my shop and dropped my fuel pressure test gauge. I was looking on-line for replacements…just the gauge…but they don’t list them for liquids, or air pressure etc…
I’m under the impression that any gauge in the 0-100 range would be fine.
If a gauge is properly connected and held above the source of pressure liquid shouldn’t enter the gauge. But what on your gauge is broken? The mechanical gauges are bourdon tube
I dropped it and when I inspected it, the needle read just above the max pressure…I think it is 100#.
I thought that the needle just jumped over it’s stop post. I took the cover off and used my finger to rotate the needle clock wise enough and then slip it over it’s stop again.
When I hooked to my truck…which should read about 40# …it only rose to about ten # and it took at least a minute to rise that far. Nothing leaked!!!
Check your gauge with air pressure.And FWIW any gauge or sending unit can be tested with controlled air pressure. If your gauge measures 0 to 100psi connect it to 50psi and if the gauge indicates 50psi it’s working OK.
