Yes it is a Carter 4070. I will check polarity again. It is a noisy thing. The fuel line is fed from the selector valve. One side of the selector valve goes direct to the primary tank the other side goes through one of those little Chinese electronic pumps to the secondary tank. The pump is wired to the selector valve so when secondary tank is selected the pump runs. The output of the selector valve goes through about 4' of 3/8 tubing to large canister Summit filter and then immediately to Carter pump. It is then pumped to front of motor home to FiTech fuel cell which has a tank and float valve and a submerged high pressure pump that pumps fuel at 55 psig through a secondary filter to the throttle body. The tank has a vent,( vented back to the gas tanks) and high and low pressure gauges.
I put the pump and filter in first and ran 200 miles with mechanical pump and carb still installed before I installed FiTech system.
