Looking for info ... 1950-1951 Willys Overland 6 Cyl flathead A picture of fuel pump vacuum lines and air cleaner hose to manifold ? Guessing that where it goes... As for fuel pump one line goes to windshield wipers not sure where the other goes .. there’s an upper and lower.. Thanks in advance ..
On a two stage pump the upper chamber is a vacuum booster and the line goes to the wipers. It should tee into the vacuum line from the engine in some manner. The line from the lower chamber will have two connections. One comes from the the tank (inlet) and the other (outlet -pressure) goes to the carburetor. If you don't have both original lines, remove the fuel pump to see if it is marked "inlet" and /or "outlet. If not, work the pump lever by hand with a finger over the hole(s) to identify.
