For some people smarter than me. Now I know that this is technically on a 1960 Land Rover Series II 88, BUT the fuel pump is feeding a single barrel Holley for a 60's GM Truck inline 6, that and other parts have been GM'd in the restoration. So the engine is a 4 cylinder 2.25L petrol (its British) motor I am trying to get back around to restoring the rover, and an issue I have been having is with the fuel. It currently has an electric fuel pump (and has for many years) instead of the mechanical pump. A while back I had the rover running and the carb started over flowing. I thought it was an issue in the carb and eventually replaced it. Over the weekend I had the pump on (hadn't started it yet). Heard the pump shut off then it kicked back on and all of a sudden the carb started overflowing. I am thinking that the pump is putting more pressure than the float is able to stop.Not sure why this is a more recent issue and not sure if the electric pump has an internal regulator that isn't working. Its an old universal pump that is just on the frame and will have to check the ratings. My dad said at the time he did the conversion the electric was cheaper than the mechanical but doesn't seem to be any more. The mechanical is $45 and I can get some 4psi electrics for about the same but then get expensive after that. Question, is it just as easy (better) to go back to the mechanical pump or get another electric (I honestly don't even know what I should get as far as PSI ratings, but know it doesn't need to be high)?
