Something to check if your supercharged

I recently was inspecting my MAF and during my inspection I noticed that the fuel regulator line going to the rubber boot was not drilled completely through. I removed the hose from the regulator and could not get air in eather direction. I did confirm with Magnuson that it should be completely drilled through. It's easy to test, just remove the vacuum hose from the regulator and see if air passes back and forth.

Anyone getting less than 10 mpg with stock tires I would have your fuel regulator checked and or injectors.

 

Good to know. I'll be under the hood tomorrow so I'll double check it.

 

John and I spoke today. Mine was clear. Very strange.

 

Must have been made on a Friday, my fault for overlooking during install.
