Question New 383 LS1, which fuel pump?

Got my 383 running and now during tuning the car won't respond to increases in fuel. I'm assuming my Walbro 255 that is about 7-10 years old is shot. So, question is, replace the 255, Racetronix kit, or Aero 340? Thanks, Chris.

I would go with the Racetronix... but first I would verify the fuel pressure is dropping to rule out any other fuel related issues.

I only have a gauge on the rail. I'm getting about 56psi at idle but I'm sure it's not having issues until it's under load. Is there any way I could monitor it under load besides a dyno without buying a guage pod?

Get a remote gauge & tape it to the windshield.
