Default fuel pump wont pump

Brand new fuel pump on the car,ran fine for a few minutes earlier in the week,but today no fuel.so I took off line pre pump and plenty of gas running with gravity but no gas on outlet side of pump. The motor is fresh with less than an hour on it.Am i missing something or do I have a bad brand new pump?? Thanks for any advice.

When you replaced the pump did the pump rod fall out of the engine? I'm sure you have checked this already but this is the only thing I can think of if you have gas going to the pump but not up to the carb.

I once had a problem with a pump because the rubber hose connected to it must not have been making a good seal. Mine was on a Blazer and it had a flexible hose so I just cut off an inch to get to a fresh piece of hose and it worked fine.

Well the rod did slide down and i pushed it back up and put the pump back in it went together good. I guess I could take it back out and check everything againg but i Ithink its a faulty pump.

Remember that NEW stands for Never Ever Worked. Could be a defective pump!

I had a Holley mechanical 110 GPH that was a dud out of the box. What brand of pump do you have

yeah make sure you have the push rod up all the way, get another pump and try it again. It sometimes takes a few cranks to get the fuel into the carb and get the float bowl full.

It may sound stupid but I have had to pull the carb line off and suck gas through a pump, to prime it. Worked great ever since.
