Blaster Pulse line question

[jetx]

Could using a soft tygon pulse line cause a lean condition? I am dealing with
A lean condition with a single 46 on 62t cases and ATP manifold and was thinking the soft line is not producing enough vacuum to deliver the fuel properly. Am I on the right track thinking this? Thoughts?

What's your pop-off pressure? I've had to run 12-14 lbs on my single 46 to get the response right.

use a stiff walled line for pulse line

No I have used tygon tubing on the pule line for years without issue.

I've still got to check the pop off but it runs pretty good, no bogs or hesitations the plugs are just white and the other light gray.
