[Roadsters] fuel pump questions

[Tim]

After adding the banjo bolt screens, a new fuel filter, and the proper size fuel lines, I had the 2000 out this evening. She ran strong, up to 90 mph before I ran out of straight road. No sign of the issue from a few weekends ago that stranded me. I didn't get the best fuel pump output when spinning the motor to test the pump, but the float bowls are now more full than when she stranded me last month. 

Does any one have pictures of a bad diaphragm and can any send me a picture of a good diaphragm? 

Can I assume the fuel pump valves go bad as well? 

If I end up needing any of these bits, who sells them? Are they available "after market" and how do you all know about/find out about any parts that are still available aftermarket?

TIA

Currently with two running Roadsters but one might have a weak fuel pump.
