I use a 1" wrench to get it out.  Only works with all delivery vanes out though...

That pump needs a good cleaning, which I trust will be done before re-assembly? ;)

Shoot guys we gotta do a" homemade pump/engine tool" thread...
i got one...
same but different..
dad made this up on the bridgeport quick to remove the delivery valve in the vehicle. ..can be duplicated with a grinder/cutoff wheel and a solid chunk o' steel
He even put a coupla flats on the top to use an adjustable wrench on
shoot ya may even be able to grind on a socket,but it may flex too much if that sucker is tight,like mine was

Grind that slot like 2 inches deeper and ya got a valvespring compressor tool where u can reach in and grab the keepers with a magnet....
make a little stub on the end and u can chuck it in your drill press,and use your drill press to compress the springs...
i got 2 drill presses..a beater one and a nice one
yea even at my old engine shop,they used an adjustable wrench,but on the reassembly they used the ground out socket,as described
Throttle cables ftw

Like I said, the triangular nut seals metal on metal to the end of the bore of the plunger.  There is a thin machined ridge that seals against the distributor head.  The o-ring is outside that metal on metal seal and merely seals the edge of the triangular nut against internal pressure.  The area of the triangular nut inside the metal sealing ridge sees injectionl pressure, but the o-ring does not.  

AH HA!!

thank you for the explanation.. i totally understand now.
