My general assumption is that the factory pump may just be worn enough to lower the output pressure to something the Weber is fine with.

I know everything I've read about Weber carbs as they relate to line pressure is: They are very very picky and even a tiny bit too much pressure will cause issues.

I have a 38/38 and it was suggested perhaps I get a fuel cutoff solenoid off of EBay as mine likes to do the same. I believe it replaces the main jet.
I was wondering the same thing. That has been the "source of my confusion" so to speak.

If a Carter outputs 4-6 psi and the factory mechanical provides even less pressure and folks say they run a Carter w/o a regulator...wait...WUT?!?!?!?!?

Those factory components are incredibly durable if my pump has 345K on it and is still pumping it's ass off to beat the band is all I can say.

I have read many posts by somebody (Pennyman?) that say a pressure reg will burn up the mechanical pump in short order.

Why won't it do that with an electrical pump then?

I was a auto dealer service writer by trade- 20+ years- so I know just enough to get me in trouble. LOL
