Michael, 
I wouldn't worry about exactly how much fuel is pumped. In a minute, I 
would think that you'd get about a quart and at cranking speed that would 
be plenty, maybe more than plenty. I think personally, that the volume 
test is more indicative of problems than the pressure test. The best way 
to do a pressure test is to put a small gauge in the line with a Tee, but 
this is probably more than you want to do, and you can certainly get an 
indication with one of the cheap vacuum guage-fuel pump pressure gauge 
devices that you may already have. If I were to put in the small gauge, I 
would leave it in place, in fact mine is in place. I think somewhere 
between 5 and 9 pounds would indicate the pump is OK, but only the volume 
test can tell you whether it is really pumping gasoline. For God's sake, 
be careful when doing the volume test as "cooked chiropractors" aren't 
really considered a delicacy.
