should check the oil pressure switch first if that does not fix the problem than connect a oil pressure tool to see if u really dont have oil pressure. if got good oil pressure around 35 to 65 psi any thing lower replace oil pump.
I would try the cheapest route first Go but a oil pressure sender to see if that fixes the problem
Do a pressure test. We need to know what engine you have to give you the pressure specifications.
Fuel pump pressure (Maximum) 75 psi
That would be best left to a repair shop. You will need a pressure bleeder.
Need oil change or oil pump weak or oil pressure sending unit not reading properly.
Pressure booster pump Many people confuse pressure with velocity to increase pressure you need a PUMP
Bad oil pressure switch - $10 Clogged intake screen - $?? Bad oil pump - $1000 Worn bearings in engine - $a lot
The 2000 GMC fuel pressure regulator is located behind the injector fuel pump. The injector fuel pump and the fuel pressure regulator will be on the top of the engine.
No you don't need a tank to simply pump water from a lake. You would only need a tank if your using a pressure switch to turn the pump on and off.
you will need a fuel pressure and flow gauge and then check actual meaured to specs.
That is a sign of a bad fuel pump
You will need a fuel pressure gauge.
To compute the power of a submersible pump, you need the pressure and the pump power.
