62' Newport, I am replacing the fuel pump for a lady on this model car. I have installed the new fuel pump. I checked the rod and its straight, I put the pump in and nothing. Its not working, I tried priming it by sucking fuel through the pump. It will squirt 1 time a long line and then nothing. I can feel the rod making contact and I am just lost. I have removed and re-installed 10 times atleast with the same results.

WHAT AM I MISSING?????????

I did measure that the new pump arm is 1/4" longer than the old one. Is this just a bad pump???
If I press it by hand (Extremely hard to do) it seems to work fine. Its almost like the rod is not long enough to push the pump in all the way but the rod shows no sign of wear that I can see. We are going to compare the used rod to a new rod and see if there is some diffrence but this one has me STUMPED!!
THE MOTOR WILL NOT CRANK BUT WILL WITH STARTING FLUID THATS THE PROB
 
That pump should deliver a squirt ( about 1 to 1 1/2 ounces ) about every 3 to 4 seconds when cranking. It only pulses one time for each two revolutions of the crankshaft.

Put a vacuum gauge on the intake (fuel tank) side of the pump.

Crank the engine - the pump should generate at least 15" of vacuum on the first pulse and build to 22" or more after 3 to 4 pulses.
If no vacuum check the cam inside the engine for excessive wear. and repeat the test by hand pumping the the pump lever.

If the pump generates good vacuum then the problem is that there is a hole in the fuel line letting air into the line. This is quite common on older vehicles and a 62 has certainly been around long enough to rust through a fuel line or for a crack to develop in the flexible hose at the top of the tank..
