I had a longer then normal starting issue (it would take a few seconds of cranking to get the engine to catch). I pulled the Vac line off the FPR and there was no fuel in the line. But there was a faint gas smell but other wise dry. I replaced it with a BWD unit Part # 24027P from O'Reilly'* for $50.00. After the install the engine starts instantly and has better throttle response then it did before I replaced it. I also went and replaced the fuel filter also with a Wix filter.

That is good news that the FPR has yor have Bonny running well and starting properly again.
Changing the fuel filter, good plan!!
Here is a good video on the FPR. After running and removing the vac line, it takes about 3-4 minutes for the failing diaphragm to leak & show it'* in bad order.

Thanks for posting your fix.
