I'm using the fuel consumption on the dash + when i do the math mileage driving vs how many liter I put in the tank.
All the number have increase on mpg.
I check the top of the housing , there is no leak.
Does the fuel pump have a pressure setting valve are something like that?
By the way, the car use more gas, I tried for fun the top speed, because if it use more fuel, it will go faster, well... on "close road" I hit
180km/h at the speedometer when i used to reach max 175.
