Fuel Pump Issues need diagnosis

[Bakeman]

Howdy folks,
I recently began restoring a '66 Monaco 500 w/ 440
It's rough looking, but a California body, so worth restoring. My first goal was to get it started.
With gas fed into the carb, it runs well - for about 10 seconds.
I put in a bypass fuel tank, but there was no suction.
I replaced the fuel pump and still no suction.
Can the cam be worn off?
Can the push rod be worn down?
Any ideas out there?

With a new fuel pump, next thing to look at is the rod that works it. The fuel pump pushrod.

They do wear, so a new one probably is in order. Be sure to get one with hardened ends, but for now, anything "new" will do.

Please keep us posted,

Great car. Yes the push rod can wear, might be one of the reasons the car was parked. I would get a new pump, remove push rod and check length. There have been some good discussion on here about the pushrods. I don't trust the after market rods as I have had those fail on fresh engines, I find NOS rods when I can. When a rod goes it can take the cam lobe with it like when lifters wipe a cam. When that happened on my wagon I killed two push rods, so I installed an electric Carter pump.

DO put some cam assy lube on the pushrod ends when installing it. Just for good measure.

Thanks for the quick input.
I have read through previous posts. My problem is that the push rod doesn't come out! It slides in and out about 1/2", but to won't just slide out.
I'm back in the shop this afternoon. I'll let you know if I have success.

Might be some varnish accumulation as the shaft is basically straight.

Are you taking the plug out?

I'll bet you are, but I've found that sometimes it's best to be sure.

A long pair of needle nose through the opening might help.
