The larger line is the pressure line, the smaller line is return.
maybe the fuel pump is not supplying the fuel as it should check the fuel filter and the pump pressure or the air filter is clogged
All filtration systems have a recommended operating pressure. It's probably listed on the label of the filter. Generally speaking, a clean filter will operate at between 10-15 PSI. When the filter reaches 10 PSI over the starting clean pressure, it's time to clean the filter. Remember, a slightly dirty filter actually works better than cleaning one too often. thepoolandspawarehouse.com
should be mounted on fire wall,passenger side, REMEMBER TO RELIEVE FUEL PRESSURE FIRST !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
when the pressure is high on filter mode it usually means that a backwash is required.
Usually the pressure gauge on your pool equipment indicates how much pressure there is before the filter. as the pressure goes up it indicates that the filter is getting blocked and needs a backwash or cleaning. while the pressure is low the filter does not need cleaning.
If I remember correctly you have to remove a little trap door. When under the car you will see two screws, loosen those (they are quarter turn screws) and move the door. You will see both the drain plug and the filter. The filter is up a little ways.
There is a certain amount of sediment in all well water - it is coming out of the ground remember. Every well should have a sediment filter before the pressure tank.
As the filter gets clogged it restricts the flow of water and the pressure in the return line drops. The pressure gauge on the filter itself indicates the entry pressure and that will go higher as the filter becomes clogged. Don't ever allow the pressure to reach 40 PSI. Back-washing the filter should restore the pressures. Pool Masters
If you can blow through the filter with no constrictions it's fine.
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.
I suppose. Was that the pressure when the filter was new of very clean? No 2 filters will be exactly the same.
Because When the filter is on the water is being pushed through the sand, this brings about a buildup of water pressure in front of the filter and a reduction of water able to get through to the returns. If the filter gets dirty the pressure gets even higher. When the system is set on recirculate the water bypasses the filter so there is no pressure in front of it and as a result of this it is able to move through the system more easily.
