250 I6 Monojet Fuel Pressure Requirements

[grancuda]

Anyone know what a '72 Rochester Monojet fuel pressure should be? I put a 3/8 line all the way up and a holley electric pump on for when I do my LS swap and it is making my carb run funky. It is putting out 7-8 psi and I think the Monojet should should be 4-5 but can't find that anywhere. I am planning on getting a regulator for it but need to know the pressure I need to shoot for first.

Here's some info for later sixes but it should be about the same.

Can't say for sure for a '72 however, the factory manual for my '69 states that it should be 3 to 4 1/2 psi for the 250. As far as volume, it should push out 1 pint in 30-45 seconds.

How do you test fuel pressure on the 250 l6? Can you just turn it over or does it have to run?
