Model B Fuel Pump Issue
 

I'm not getting any fuel to the carb on a 1932 Model B motor. I've cleaned out the tank and the line, replaced the fuel pump, and have isolated the issue to the pump itself...it doesn't seem to be pulling anything from the tank at all (when I cleaned the fuel line it was bone dry.)

I've never read of having to prime a pump like this before but at the same time, I'm kind of stumped. There's no secret to installing the pump, right? I put the rocker arm in the hole/boss on the side of the block, feel it tilt as it connects with the cam lobe, bolt it on, and connect the lines...am I missing something? Any ideas?

Thanks!

Maybe the pump arm is not the correct one and is not moving enough to move fuel???

You say replaced the pump ? what with , if rebuilt maybe need to pull apart & check as valves could be wrong , Take it off & work with your hand & see if it sucks ,

What is the full story? If the B engine is in a Model A vehicle just hook the gas line from the tank to the carburetor. If it is in a Model B you posted on the wrong forum, post your question on the Early V8 Forum (they let the banger guys in also).

Just check the pump off the car. why was the pump replaced anyway?

Hey Cris,
'replaced the pump'...can you say why you replaced the pump ? Was the pump that you replaced....an original '32 fuel pump ? And, did you compare the (possible) original pump, with the replacement pump ???
I ask these questions, to maybe pin point your problem. MANY pumps are out there that are said to be adaptable to the '32 B engine.
My guesses: IF replacement is an original...improper rebuild...not uncommon! If replacement is NOT an original, but in good working condition otherwise....wrong pump ARM and therfor pumping action. Not hard to figure out,eh :) !
BTW..there are markings on original pump carcasses to help id.

Sorry if you do have but just need to ask? You do have gas in the tank! Also the tank is venting? Can you pressurize the tank and get fuel to the pump?

I still want to know what year the vehicle is? There is something missing. How about a couple of photos?

You found the line dry, so loosen the fitting at the pump and let fuel flow that far, then tighten it and try the pump again. If it still doesn't pump then I'd take it apart to check the diaphram and check valves. Corn crap gas has destroyed the diaphram or stuck the valves, or both.
