Fuel pump for 9.9hp 4 stroke

[roehrle]

2009 I had to replaced my fuel pump. I thought this time I would get the replacement parts instead of buying a new pump.
When I took the pump apart the two check valves were out of there housing.Not sure of why they came out I decided to go back to a new pump. Now 5 years later the pump is acting up so I was going to order a new pump (435352). To my dismay I found out that they no longer are making this pump. I still had the repair kit (435070) that I was going to use in 2009 that hadn't been open. I took out the pump and once again the check valves fell out of their housing. This time I had to try and replace the check valves which I did. Once replaced the motor ran for 16 minutes at 2500RPM and stalled. I pumped the bulb and it ran for approximately the same time before stopping.
Here are my questions;
I think that the check valves didn't stay in their housing and the motor was running on the gas that was pumped by the bulb..??? I think this is a possibility that gas can get still get to the carb with the check valves popped ??
Anybody know what would cause the check valves to pop ?? I had 3 other old pumps that I had saved and when I took them apart the valves stayed in their housing. I can still run the motor by pumping the bulb every 15 minute but why should I?
Anybody know if there is a replacement available for the 435352 ?? Any thoughts on why the check valves popped on me two times??

Another piece of info
I tried to remove the check valve from an old unit and could not get the parts out.... What made them come out on two recent pumps all by them self ???
Could it be later pumps were defective ??

You said the magic word, Defective. Can you make one good pump out of all the parts ??

No Title

I'm going to use the middle section of one of my old pump that contains the check valves. I hope i picked the best of the 3 that i have..Here is a photo of the one I will be using

From the pic it looks okay.

I took the middle section, which contains the check values, of one of the 3 pump I had replaced in the past and installed it in the pump that I had just rebuilt. When I took the latest pump apart the check valves had also popped out . That being the third time this has happened. I installed the middle section and happy to say it appears to be working now.
Lesson learned, Don't throw away old parts, Don't buy BRP stuff.
