Finally got around to building my triple walbro hellcat 525 setup

 

That looks insane!!! How much power you planning on making?

 

i wouldnt think there is any way that siphon system is going to work with that much flow.
maybe im wrong.

looks good tho.

 

This might help....This is from Radium...
One major issue with the OEM EVO 8-9 fuel pump hanger is the restrictive return port and venturi jet pump. When using aftermarket high-flow fuel pumps, the OEM jet pump becomes too restrictive creating unwanted back pressure in the regulator return line causing excessive fuel rail pressure. The Radium fuel pump hanger includes a venturi jet pump with a new integrated pressure-relief valve to minimize back pressure. All returning fuel from the pressure regulator and crossover hose exit the jet pump keeping the OEM gas tank baffle full for starvation protection.

I will be trying the radium ventiri jet pump kit. I just installed the stock one for looks.

 

I guess I just don't see the point of this. Seems way harder to work on then building a surge tank and using actual big pumps like AEM 400LPH 044's..

And/or running a mechanical pump since a double pump Walbro 525 setup will make 1000whp on E85.

Also, that stock return Venturi will not flow enough. You should consider revising that with what radium offers.

 

Why on earth do you need three 525's???

I'm also with letsgetthisdone. Highly recommend getting the radium venturi.
