Im currently doing a full build. MAP 2.0 hks 280 cams, 2150 injectors, MAP turbo 525 pump, bulletproof fuel hat and a few other goodies. The only thing I dont have ordered is the fuel pressure regulator and filter. Im looking at a fuel lab 515 series. would I want to go with the 25-90 psi or 90-125? This will be on E85

 

I did an Areomotive fuel filter and a magnus afpr on my car. Remember your fuel pressure will be at 50 lbs with the 525 so I would go with the higher gauge

 

Thank you. I forgot to mention I will be -8an feed -6 return

 

Yeah that will be more then enough to do what your looking to do. Idk what your goals are for the car but sounds like a good solid foundation for fuel. I know I got deals on both my afpr and my filter was free so I couldn't pass it up.

This is the filter I run in my car

I recently put a radium fuel filter in my evo. The mounting system they have for it is really nice, and makes for an easy install.

 

I looked at aeromotive but they didnt have a polished one the was e85 compatible for 10 micron

 

Another vote for Radium. The filter setup is top notch.

 

the 515 would be fine...

im not sure what you mean by this.
would I want to go with the 25-90 psi or 90-125?

do you mean on the gauge?

 

I know im going a bit overboard but id like to hit 550 on low boost and whatever on high boost

They make 2 versions of the fuel pressureregulator. One designed for 25-90 psi and one for 90-125. At least thats the way it appears to be

 

Base fuel pressure should be set to approx 43psi so you would want the 25-90psi version
