The ''Grease Trick'' doesn't work in AZ, especially in the Summer. It just oozes away, and won't congeal. Might work in Michigan, or Fairbanks, IDK.
I was happy to discover the Bolt Trick. At least it works on my SBC.
I don't have an operational big block currently.
And L6s have direct contact with the fuel pump foot touching the cam itself. No pushrod needed.

The issue of Quality Control of mechanical fuel pumps is a serious one. Not even AC Delco is trustworthy anymore. Mexico, Korea, Taiwan or China. Even an NOS, USA-made one might be compromised by modern fuel formulae.
A couple of years ago, I went thru 3 in a row, until I got a pump that worked. One lasted a year, the next one didn't survive a trip Downtown.
I think it's the Ethanol that's mandated to be infused with Mogas now. Eats the rubber in the diaphragm. But I'm not a big fan of electric fuel pumps.
