Fuel Tank/Pump Question
I recently tried to dump all the fuel out of the car by jumping the fuel pump relay and only got about 5-6 gallons out of the car. Measuring the resistance on the senders I get 60 ohms driver side and 260 on the passenger side. That leads me to believe I am only emptying the driver tank. My question is, does the jet pump/siphon in the passenger tank work without back pressure in the system? I have a -6 line out of the fuel filter that is just dumping into a 5 gal jug instead of the fuel rail so no pressure in the line. I am thinking this might prevent the siphon from starting? Trying to determine if I need to open the passenger tank to clean the jet pump out or not? Thanks!
