Branson 3520r power loss

   / Branson 3520r power loss #11  
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.

I removed my OEM filter assembly on my 3520 - same as your picture- because the hose fitting was leaking and after examination I discovered that the hose fittings were only glued into the housing. So I replaced it with a clear inline auto type. Additionally, the OEM fuel pump has tight tolerances and my pump stopped due to a tiny spec of debris- so I installed the same clear inline auto filter before the pump and haven’t had a problem since.
