Hey,
greetings from the Czech republic,
I think I have a problem with the inflow fuel into the fuel pump from the fuel tank. It is not clear to me why the fuel pump moment spewing gasoline normally after a while begins to spitting the air with gasoline (a lot). The car then acts as the driving normally and once in a while just starts omitting - I think that air in the fuel system is everywhere - error immediately p0300,301 .... strainer in the fuel tank is clean when ... I take out the pump and the hose from the fuel tank flows only a small stream fuel. Can you think of anything? Or is this normal? I enclose a video. Thank you for your advice :-)

I agree it would either be a problem with the pick up (clogged or sucking air) or just the pump is going bad. Is it possible to route the inlet side (with a length of rubber hose) into a good can of gas and run the pump as you did in your video? That would prove or condemn the pump with the results.

Thank you for noticing. The pump is good, I tried to suck pump five liters of petrol into cans. It was done in a moment .. I'll try to find more air into the tank (but I tried it with the lid open). Strangely, the supply hose from the pump to flow out once ca 1dcl gasoline and then just a trickle ... wait a moment and again 1dcl ... it repeats ... Does anybody have a drawing inside of the fuel tank (not much in the manual)?

 

Does the pump run continuously at the same speed? Or does it change its revolutions per minute?
If the problem lies within the tank then apart from the level sending unit it is not repairable.

 

Pump, which is connected to a can works fine. I do not understand inflow from the tank ... it's just a small strainer and flow is fine.
