Worked well and fits well.

I was able to set the fuel pressure to exactly 42.5 pounds as stated in the service manual. Two things can improve this product. The vacuum port needs to be rotated 90 degrees to mimic an OEM port. Install a lock nut on the adjustment stem. I added my own nut and tightened it after adjustment.

Pros
  • Feels good
Cons
  • Not the best
