Branson 3520r power loss

[Rewsi1967]

Tractor runs idle, under load or driving loses power, question I have is, does the fuel pump run when key is on, tried filling a bottle but when turned key nothing happened

Pretty positive mine does

Mine on my Branson 3725 sure does. It starts clicking when the ignition key is turned on.

Yes, you should be hearing the put clicking with the key on. That may indeed be your issue. I would check the fuses before replacing it though.

The Pic with hose circled had no fuel in it, I was going to use the hose in a bottle to pump fuel into it but nothing when I turned key on, can I jump the fuel pump manually by direct hook up to battery. If pump is bad why would it run w at idle ?

Your lift pump provides fuel to the injection pump. The injection pump will pull fuel but that is not what it is designed for, it was made to push fuel, so when you throttle up, it cannot keep up with itself, starves for fuel, and will cavitate in time, requiring a rebuild or replacement. Your lift pump should be "clacking" as soon as the key is turned to run, feeding fuel to the injection pump. If you don't hear the "clacking", you either have a power issue or need a new fuel lift pump.

Fuse blown so far, will keep updated

 

[Rewsi1967]

So replaced fuse, turned key on fuse blew, removed pump tried to jump it with clips and battery, nothing happened, looking for replacement now

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

 

[Gregster613]

I've got an aftermarket on mine, runs fine.

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.

 

[Rewsi1967]

New pump, ran fine until warmed up, 1st gear low 2000 rpms full throttle

 

[Rewsi1967]

follow up , after replaced pump , still no power- finally got a chance to troubleshoot it, all pics was flow rate for 15seconds 1st pic is before filter , 2nd pic is going through filter and third is with no filter in it, problem I believe problem is filter, order new one same as original online be here Tuesday hope it fixes it, got 14 acres to mow.

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.
