Why does the pipeline pressure drop when refueling?

Thread Content

When filling the fuel tank, the pressure indicated by the gauge 1 meter from the fuel pump outlet dropped suddenly (from 10 to 5 kilograms); after the fuel was added, the pressure gradually returned to 10 kilograms.

Is there a foreign object inside the oil pipe? !

It is possible that bubbles formed in the fuel inside the tank during refueling caused a sudden drop in the pressure at the pump outlet.

I was wondering, what is the temperature of the fuel tank’s email when you refuel?
