( neither are for sale btw ) Im told the 4024 might be the original off my car. As the engine in my car has an assy date of early March 1966 Are they both the same PSI rating ?

The orig hemi has a large internal volume/displacement. So it would source more fuel per stroke. Constant volume pump. I have posted pictures of the internals before. The the other is a later competition pump advertised as higher pressure.

I bought them while back east last week They are being shipped to me as I wasn't going to try and get them on a plane Once back in my hand I'll get a few more pictures of it The OEM pump will get rebuilt and put on the shelf as a just in case I need it part.
