Is Alphagan Eye Drop Effective in Reducing Eye High Pressure?

The regulator reduces fuel pressure at idle. When deactivated, your fuel pressure will be high, possibly reducing fuel efficiency due to rich operation. You should install a new regulator when possible.

Aluminum alloy die casting is the casting process that injecting the high temperature molten aluminum alloy liquid into die cavity with high pressure and high speed for moulding. Features of this casting method are product precise forming and high production efficiency. However, the conventional die casting process is defective. Because the gas in the mold cavity cannot be eliminated effectively, the gas in the mold cavity cannot be eliminated effectively, and the inner parts of the casting can be left to form the defects of the pores, to make the mechanical property of the casting poor. In order to solve this problem, people use the method of vaccum pumping, that is, the gas in the cavity of the die casting can form a certain vacuum or negative pressure state, thereby reducing the inner hole defect of the casting.

As with any hot water or heating appliance, a hot water boiler system requires a constant pressure flow to maintain the optimum temperature. Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops. Despite the pressure reducing valve, owners should be familiar with the standard PSI of their hot water boiler system and should check the pressure reading regularly.

Fuel pump relay is in cavity A in the rear SAM ( Signal Acquisition Module.) on the left hand side of the trunk behind a door.

When did you check the voltage..... you must read it while cranking or you will get a zero voltage reading.. The low pressure tank pump builds pressure to the high pressure pump and then shuts down until a pressure drop is sensed in the low pressure line and it then starts up again.

If rail pressure is too low, it often is the high pressure pump in the engine or the relief valve in the fuel rail. The tank pump is low pressure just to stop the tandem pump from cavitating by sucking too hard.

Mercedes can check the rail pressure and do an injector pressure drop to rule out a leaking injector.

If the tank pump is bad it will require replacement.

This is odd but somewhat normal. This is the way the electronic gauges register. You can try to replace the oil sender to see if it registers different but as long as it shows some increase in pressure when you rev up you should ok. When you put in gear the RPMS on the tach will drop , thus reducing oil pressure. Also,not knowing when you changed the oil last you may just have worn out motor oil.

Set your timing when u remove the oil pump it will surley affect the timing on your motor.... do this with a timing light and and adjust timing by rotating the distrubutor.

When the engine and oil are cold it will show a high pressure because of the viscosity of the oil. When it warms up the oil is thinner. If it doesn't drop below 20-25 psi at warm idle I wouldn't worry about it as that is normal.

Fuel pressure at the injector rails can be high as 180 pounds but usually is around 45 to 95 PSI. Caution ware eye protection anytime you work with gas lines under pressure and keep a extinguisher handy!

Hi I am Vortash sounds like you have one of four problems either the oil you are using is inferior and you need to upgrade to a better one synthetics are best ..
Your Oils pump is failing reducing the oil pressure ..
Leaky gaskets allowing pressure to ecape .
Or more drasticaly your main bearing shells are wearing giving the the oil more ways to escape under pressure . this is usually discernable by a knocking or rumbling noise especially on tick over .. hope it is just the oil for your sake regards Vortash

No problem with the oil pressure, the norm is between 40 to 60. Anything lower then 40 you have low oil pressure and anything above 60 then you have high oil pressure which is caused by a blockage in the system.
What is common is the oil pressure gage fluctuating for the first 200 miles if the oil pressure sending unit is getting worn. Good maintenance will keep the engine clean and running good but the oil pressure sending unit is inexpensive and easy to replace. Next time you do an oil change you can have them change the sending unit.
Good luck and hope this helps. You can pick up the sending unit at Auto Zone and most auto parts store and will have the step by step to replacing it. If you do attempt to replace it. make sure you DO NOT USE any Teflon tape or silicon on the threads, they are tapered and need a good ground to the engine for proper readings.
