Branson 3520r power loss

Can I use an aftermarket fuel pump 12v should be universal if I'm correct

Just check to confirm that the replacement lift pump has similar flow rate and pressure. I believe the pressure is the biggest difference on models.

Some of those housing had an inlet screen built into them. You may have some garbage in the inlet of the housing.
