I need to get an adjustable FPR to outboard it from the fuel rail as my squaretop and radium fuel rail don't have much room for the stock FPR.

What are the model recommendations - aeromotive, fuellab, radium, ....

Will be using 5/16 barbs so an NPT style would be fine or any AN to Barb would work

 

I've been using an Aeromotive one for 8 years and it's been great.

 

+1 for Aeromotive

 

all of the mentioned regulators work just fine. take your pick

 

Been using Fuelab for ~10yrs personally.

Fuelab Fuel Pressure Regulator

 

The Fuelab Mini FPR is a solid option in a very compact footprint. You can use our EGR/FPR Bracket with it as well!

the vendor presence is strong this morning lol

that makes your decision easy OP, buy the above and support our vendors

 

I will just add to the FuelLab mini working great.

Be cautious of the Radium using oem pressure caps. Regulation struggles when adding a fuel pump bigger than 255lph

 

 

they use oem bosch style regulators

 

 

Out of lots of FPR's I've seen actually tested on a bench rig Turbosmart came out on top. Aeromotive is right there as well.
