Fuel Pump set-up

[dgrinnan]

My project, a 1947 Dodge WC was missing the fuel lines and fuel pump.  I have purchased what is supposed to be an OEM fuel pump.  I have two basic questions.  I have not replaced fuel pump in years and am not sure about the setup. 

 

1) I have seen pictures with the glass pointing up and pointing down.  Mostly up.  Is that the correct orientation?  Clearly if the orientation is wrong the pump arm will not engage and operate. 

2) Which is the inlet and which is the outlet?  Is the line coming from the gas tank suppose to go to the connection closest to the engine(arrow 1) or under the glass dome(arrow 2)?

Sorry, i cannot answer your question, but I would not install that on my car. I cant see how that upright bowl will collect any sentiment. I think you received the wrong pump. JMHO

That was one of my two questions.  It can be installed up or down.  Are you saying the glass bowl should be down?

Glass bowl down. Inlet is by the glass bowl, outlet is nearest the block.

 

At least that is how the pump mounts on my old Plymouth’s engine.

Perfect.  Thanks for the input.

And I believe you can clock the top if needed to fit in the space.

Yes, glass bowl should be hanging down. It is a sediment bowl, designed to separate any larger particles out of the fuel and collect them in the bowl. The inlet is at the sediment bowl and the outlet is above the pump body.

Agree, and the final determiner is the actuating arm.  When removing the old one, always note the arm direction.  And whether it is over or under the cam.  Those are the things that make it work.  If the glass bowl is up when the arm is correctly located, you have the wrong pump.  That procedure works on every engine, even those you may not be familiar with.

One more thing to make installation easier,  turn the engine so that the camshaft pump lobe is not pushing the arm.  . If in doubt, you can feel it through the pump mounting hole.  just turn it away from the arm.  That way you don't have to fight the spring tension while lining up the bolts.

Don't forget to dimple the ends of that pivot pin so it won't walk out of the casting...that's a nasty little timebomb these reproductions hide...
