Fuel pump push rod length
I have just searched Macs Auto Parts web site for "fuel pump push rod" - they list 4 lengths:
60 HP Aluminum intake 5-3/8" 60 HP Iron intake 6-3/8" All other V8 Aluminum intake 7.87" All other V8 Iron intake 8.87" Since the 60HP are measured in fractional inches, I wonder if the others are a truncated measurement since 7/8"=.875". This should give something to compare your pushrod to to see if it is worn.

Fuel problems
To check for air leaks in pick up lines and taps , check the vacuum with the engine running at the inlet of the pump and check it again at the outlet from the tanks .
Readings should similar . To carry out the test run the engine off a gravity can. -------------------------------------------------------------------------------- Is it sucking air at your change over tap (or anywhere else on the suction side of the pump.)(flexible hose etc) When you say the diaphragm is good, is it O.K. with modern fuel? Wet the valves in your pump and then put a vacuum gauge on it. It should suck about 15" to 18" of mercury. The delivery should be about 2-2 1/2 psi (which is controlled by the spring) If it does that, and holds it, then work back down your lines, as per my first Regards Jim S.

Another Theory
I had all sorts of trouble with my fuel pump, I put a full kit through it & it still would'nt suck up from the tank.
 The problem? The pump housing was cracked. Almost invisible... I replaced housing and away she went. I hope this helps rather than hinders...!
