Fix for Subaru GR Stumble? FPR Install!

Hey, Joe here. In this video, Tony works on replacing his OEM fuel pressure regulator with an aftermarket unit in hopes of fixing the GR Stumble.

You have 3/8" quick disconnects and you needed 5/16" quick disconnects. I'm sure you've figured that out by now. You need to get 5/16" disconnect with the same sized barb you have now though, which should also be called 5/16". Quick disconnect sizing gets weird due to ID and OD on nylon line vs rubber hose etc. Also just feel lucky this has the external FPR instead of being regulated at the tank like the BRZ or other NA cars.

Thank you for the input! He did get the correct adapters. Tankful this was a relatively easy fix.

What were the symptoms of your stumble? Mine are at 2500-3000 under slow acceleration or cruising at those rpm

[@JoeWrenches]

Same RPM ranch when trying to accelerate.

[@MrMultop]

@@JoeWrenches do you have stock injectors and fuel pump ?

[@comradeorka4351]

You need the kind of connectors that go on that part.

I believe the part number is 000000001

[@tonybucci]

Agreed

When is Tony starting his own channel?

[@JoeWrenches]

I agree. Get the Subaru stuff outta here! 🤣

[@joeslowy]

you can either stumble or spray fuel all over the engine... Its what makes a Subaru, a Subaru

A little flammable liquid never hurt anybody.
