I've just about finished replacing the fuel lines, pump, and regulator, next job is to set the fuel pressure, and give the floats and jets a going over.

What pressure do 45DCOE's need? I have conflicting information ranging from 1.5 to 5 PSI.

Cheers.

Mine ran well at 2.5psi

They don't need very much at all, I had my (delolortos) set at 1.5 with no problems. They just need enough flow.

2.5-3 psi on mine

Generally they won't flood if under 4.5 psi but aim for 2.5 to 3 psi.
