After deciding to keep my FMU because tuning issues can you guys tell if this fuel system is going work for my application?
I have walbro 340 intank and ATI's inline pump. Will this be sufficient?

 

I would try the 340 alone with no fmu/inline. If you drop pressure with that setup then add the fmu. 340 is good for 500hp.

 

94slug, i need to keep the fmu for drivability reasons. Because my sysytem is speed density. I need to know if i can ditch the inline pump? And only run the walbro 340 intank. But unfortunalty the fmu is staying.

 

oops ya that should be fine 340+FMU, but whats the ratio on the FMU? If i rem you have a 92 not sure how much hp stock lines will hold. I would run the intank and fmu only!

 

I am not familiar with the FMU ratio. The FMU is the is the one that came with the Procharger P1SC.

 

Stock lines are good to about 700hp. With the power your making the weldbro will be plenty. If your fuel pressure ever starts droping then its time for the ati inline or bigger pump.

 

I believe that the ATI units are adjustable. There is a screw that you can screw in all the way or out. If you look on their sight it will show you on their tech help online.
