Mechanical fuel pump oil leak

[LeonBlank]

Good morning!

1963 F100 223 L6

Long story short.
Removed electronic fuel pump installed mechanical pump....new tank....new lines, new filter.

New fuel pump from O'Reilly lasted under 40 miles and refused to push fuel.
Second pump from NAPA runs great but pushes oil from weep hole something fierce.

At idle I have good PCV flow proven at top of valve cover. Could I have pressure at 2-3,000 rpm?

I have 2,000 miles on a complete rebuild.

Thoughts? Besides sticking in a toothpick

Can’t plug the hole, it’s a vent hole for when the diaphragm moves. Try again with another. Some will tell you to go back to electric

This would be my third one. Now this one on the drive home the pivot pin walked out.
Dang it i was trying to have it as close to original as possible. Looks like im digging out the removed electric pump.

They just don't make stuff like they used to

You could reinstall the electric, plug the hole, leave some tubing— it would look like original

He was a learned and smart man. I tried the mechanical and gave it up 50 years ago, never again.
Electric= faster starts, when it sits for a while, especially when you run out of gas.

"Rolling my eyes" " I know I know" just hoped to get it more original umder the hood. When I first dod the mechanical pump I loved it. Quiet and fired right up. It gets driven every few days so empty carb was not common.
Same reason I argued with my wife that I wanted to fix the am radio instead of the retro sound she wanted me to get.

Look on eBay, you can find better quality units that will fit in the original hole. Retro sound stuff is cheap quality, have been disappointed with my unit
