Upgraded Walbro Fuel Pump
Well after speaking with Westech Performance a few weeks ago to schedule an appointment for a chassis dyno session, I was informed that the Walbro 255 liter pump I had in the tank would not be adequate to feed the LS7. I ordered a new Walbro 485 liter pump. The customer service at Walbro was excellent. There was some modification required to the cage which they informed me of, but minimal. After installing the pump I turned the key and I thought it had no power. It's so quiet you can't hear it. Started it up and drove it a few miles, runs great. So now I will be off to Westech on Monday morning for the dyno session. Fingers crossed no issues.
