Hello,

I notice last summer something strange about my car. I own a Mazda 626 Cronos 1994 4 cyl. auto.

When the gaz tank is half full or less and that I take a rapid turn ( like a highway ramp at important speed ( above 60 km/h ) my RPM just fall down and it seems like there is no more fuel going to the engine. The engine didn't stall but it came close each time it happen. When this is happening, the car loose speed and it seem the centrifugal force ( [&:]on the fuel inside th tank ? ) , being less important, the fuel return back to the engine and the power came back again. If the fuel tank is full or above the half level, it never did that. I replace the fuel filter, thinking it could be the problem, but the problem still happen ( seem to happen less often though ) Can it be the fuel pump ou something loosen in the fuel tank ? What are you thinking of that ? Thanks for your help and opinion. Chrysof that ? Thanks for your help and opinion. Chrys

 

It sounds like to me the small jumper hose on the fuel pump. This hose is about 2" long and connects the fuel pump to the sending unit. If it is leaking pressure back into the tank instead of sending it to the engine, this can happen when driving. If it was a baffle in the tank, I would think it would happen no matter how full the tank is.
