Default Mechanical fuel Pump issue

Hello,
Started my Mattituck IO360M1B yesterday for the first time. It was great to hear it run on the plane. Fuel pressure indicated 25psi with boost on. When I turn electric boost off, fuel pressure dropped to 8psi and the engine began to sputter. I am checking to see if anyone else had a similar issue and what they did to correct it.
Thanks in advance for your suggestions.
Tom

Did they accidentally put a carb'ed version of the pump on it?

Sure sounds like that is the case!

The mechanical pumps come in 3 pressure ranges. Carb, Pressure carb, and FI. 8 psi sounds like the pressure carb version.

I will have to get the serial number off the pump and call Mike Yousik to see what fuel pump they gave me. Thanks for the replies!
It would be really nice if this is the issue.

How is possible to receive a wrong fuel pump if they supous to run the engine and check fuel pressure before delivery. If they really assemble you engine with the wrong fuel pump you better check everything in and out of your engine
