Technical 292 Chevy Fuel pump won't?

Hey folks, I searched and didn't find the answer I need so I'm looking for help to finish up a project. I finally got time to wrap up loose ends on my '62 Suburban getting a "new" 292 I6 and 700R4 so I could break in the engine and start driving it. Much to my dismay my new Carter M3530 would not move any fuel. I blew out the lines from the tank, dropped the tank and made sure it was clean and the pickup wasn't plugged, hooked a nurse tank to the pump suction and ran the discharge into a clean can and nothing. I had the engine running from a elevated fuel tank gravity feeding the carb and the new engine runs great.
I started with a rebuilt '66 292 that I drove home 20+ years ago, s****ped the truck and put the engine on the shelf. While I was smoothing the block for this project I discovered I'd apparently left a little water in the block and it had cracked above the pan rail. I read all the how to's and tried to weld the crack with nickel rod and ruined it. As luck would have it I found a nice '63 292 that was still all standard dimensions with no taper so I cleaned it up, honed it, polished the crank and swapped in the "newer" cam and head from '66 along with all new rings, bearings, seals, water and fuel pumps, etc. I still had the old fuel pump from one of the engines in the s**** pile and it looks identical to the new one. I can feel the cam behind the pump mount flange, but he lever on the pump doesn't seem to be the right angle to reach the cam. If I manually cycle the pump lever it pumps just fine (gas sprayed in eyes).
Do I need to pull the engine and get another cam? Or cover the pump mount boss and put in an electric?

 

is the pump right side up? I think the pump is supposed to be upside down, that is, with the fittings on the top, not the bottom.

 

Have you tried spinning the motor over and see if the fuel pump rod is moving ?

 

This was my thought too

 

the lever on the pump rides directly on the cam on the six. No pushrod.

 

as squirrel wrote the pump in the picture is shown upside down. easy mistake because the boss on the block has a "triangle" shape to it in the wrong direction........guess how i know?

 

That must be it. I matched the gasket and pump flange to the boss cast into the block which puts the fittings down. I'll have to see if my new pump will pump by pulling the arm rather than pushing tonight when I get home. As I remember though, the old pump has a wear plate riveted to the long side of the arm (top as shown) and I think it has a shiny spot rubbed into it? And the spring visible in the pump pushes the arm up (as shown)? I know if you push the arm down towards the pump can it pumps fuel, but it requires taking up over a quarter inch of travel at the tip of the arm before you start to move the diaphragm? Thanks for the help guys.

Go to post #6, where the 250 and 292 pic are shown. Pump fuel threads are top side.

 

Thanks Bob, that seems to confirm what everyone else says. My memory is apparently not what it once was. I really appreciate all the help guys!

 

Memory, what memory? I don't remember any stinkin' memory!

 

292 with fuel pump mounted as it came out of the running truck.


A 250 by the way has the fuel pump in front of the motor mount and closer to the distributor.
