Maybe.
One other alternative is that the sand in the filter has become "channeled", that is, the water has worked open "holes" in the sand and is streaming right through (without really going through the sand).
Try a good backflushing, that usually fixes the channeling, if that is the problem.
If still zero pressure, then try replacing the gauge.
Hope this helps...
I think your gauge is defective. Filter channeling will provide poor water filtration. Backwashing should be part of regular pool maintenance. Check pressure after backwashing. When the pressure rises 5 or 10 pounds it is time to backwash again. Keep in mind that as the pressure increases the filter becomes more effective at removing particles but also allows less water to be filtered. Never allow the pressure to exceed the manufacturers maximum pressure rating for the filter. Get a new gauge. They cost a lot less to replace than a burst filter.
Because the pump is either loosing it's prime due to air leaking in through a crack in the intake line or a bad lid gasket, or the gauge is broken, or the pump is turned off. Hatawa The first thing to do is to check for water flow. If there is flow that feels normal there is pressure and you probably have a bad gauge. If there is no flow, is the pump running. If the pump is running look at the intake basket is there water in it if there is is there air bubbles in the water that indicates intake line or lid gasket problem. There also the possibility of a bad seal in hte selector valve. Check to see if there is flow out of the backwash line. Of course there would be abnormal water loss if that were the case.
I think when it happens when the pool starts to turn green
The gas is probably not leaking into the filter but the engine. It's caused by a broken diaphragm on the fuel pressure regulator. Replace regulator
NO!
If one bank is running lean it usually means that you have a vacuum leak somewhere on that side. Check for broken hoses that connect to that side or possibly broken gaskets. changed all hoses what gasket
sounds like a fuel problem check first for a plugged fuel filter if filter is OK, it is likely a fuel pump, if you have access to a fuel pressure gauge check fuel pressure a test port is located on the back of the manifold on the drivers side should be around 60lbs of pressure if not you probably need a fuel pump. the other alternative if filter is good and fuel pressure is good it may be a plugged catalytic converter
Probably because it is clean, leave it on the filter setting for a while and you will find that the pressure will increase as the filter gets dirtier, when it get high (usually in the red ) you will have to backwash.
Fuel filter, fuel pump, or pressure bypass/relief valve is not providing the correct, enough fuel pressure at the injectors.
Probably not , but check the owner's manual, it should list it, if it's there.
What was the reading on the gage, while the system was running, before you changed it? Eight #'s pressure sounds about right but depends upon a few things. If it is reading zero with a new gage then you probably have a suction problem or there is no water flow. If you had higher gage readings before you replaced the gage maybe the filter was dirty. Have you backwashed the filter lately? k
it will be at the oil filter probably a 3 wire plug if not on the filter boss beside under or over it but very near filter
bad gas filter block or low fuel pressure
Sounds like you may have low fuel pressure. When did you last change your fuel filter? JA
Can be, and can also be a clogged fuel filter. A fuel pressure test will verify this.
