Any lower than 15 psi would indicate a problem. But as long as you have at least 10 psi you are getting lubrication. If you have low oil pressure then change to an AC/Delco filter and 5w20 weight oil.
It should be about six inches from the compressor. The large line.
On a '99 suburban, the low pressure a/c port is on top, towards the back of the compressor, and pointed forward. The high pressure port is there also, just behind it and to the left, pointed straight up.
Fuel pressure on a 2002 Ford F150 4.2 V6 should be around 40 PSI. When pressure drops too low, fuel is not vaporized properly.
The port is located on the low pressure line. The low pressure line is the larger of the two lines coming from the A/C compressor. Also it should have a blue cap covering the port.
it should be in front of the radiator like on my 1998
No or low fuel pressure
Low pressure side of compressor (larger hose from compressor)
were is the low pressure side ac port located on 2002 lincoln navigator
YES IT WILL. It must have 9 to 13 LBS. of pressure NO less and NO higher or you will have problems.
The LOW pressure fitting is SMALLER than the HIGH pressure fitting.
tad bit low on freon.
You should generally sail with high pressure, as low pressure often brings storms.
