Unfortunately, your video doesn't appear to be at that link. BUT I did find a previous posted thread regarding your Al Franken-pump success and your old Photobucket link is still functioning ;-)

So lotsa help there -- thanks, Lonnie. Too bad the $5.25/unit prices didn't hold over during these 60-odd years, huh.

I also re-found my old factory assembly manual and voila! there it was. Btw, I forgot to mention that the engine is actually a '57 rebuild (25 years ago). In which case the actual pump for this engine (not truck body vintage) will be a metal pump with a slightly longer lever for a bit more pressure. If it can be mated to the glass top it could be a 'win' all the way around in my 'Nifty Department'!

Methinks I'll just go ahead and order the inexpensive Airtex/ACDelco metal replacement (for 1957) from RockAuto and go from there.
The worse that can happen is a 'no match' for cannibalizing, and then just use the new pump instead when the glass model finally forgets to push gas.
Oddly enough they also carry the cork/rubber glass seals for less than a buck (as well as the glass bowl w/seal) ..but alas, not those glass pumps.

Ps/ that's a nice looking truck you have ..similar color to mine -- teal green?
Nice touch with the inline gas filter. I also have one (in the toy box) with the porous stone element. That may go on the line next ;-)
