Both as it turned out. Soft fail of electric pump but probably would have gotten me from 70-80 DTE fuel starvation down to 20-30. I found a faulty o-ring in the transfer pump connection:



And then also the connection below that which has no o-ring from the factory was leaking like a shower so I added in my own design to seal that.

Now I can use all the gas in my tank. I still haven't figured out if the reserve tank is included in the DTE and from test 6 it seems like it is not. Case in point :

At 34 miles DTE the car was reporting about 9.5L on the left side of the tank. That would mean there would be closer to 18L of gas. That should get me closer to 70-80 miles.

I will be opening up the tank to find out the definitive answer soon
