That’s really helpsHi Paul,
Yes to both. The 3500S has an electric fuel pump, and it runs continuously. The reason being is the fuel system was designed with a spill return, meaning excess fuel is diverted returning to the tank. Correspondingly, the pump runs continuously. Cars with pumps that are discontinuous do not feature a spill return system.

thank you it’s all very new I sure I’ll get thereHi & welcome to V8 ownership.
The original pump would have been a mechanical one at the LHS front of the engine.
Many owners convert to electronic pumps in a bid to reduce possible fuel starvation although the jury is probably still out as to whether it helps.
