boost reference regulator leaking I'm having a issue with my regulator.
Everytime I rev the motor passed 4k rpm or so the boost reference nipple on the regulator spills a little bit of fuel. It's not a lot but it does seep out under load.
It does not leak while normal driving.
My fuel pressure is solid at 62psi and does not drop.
The regulator is a SUMMIT boost referenced regulator.
What can be causing this?

It should not leak at all...ever.......time to return it.
Edit: It also sounds as if you don't even have the reference port hooked up....as you're able to see a leak out of the reference port. As has been said previously, fuel pressure should rise 1lb per lb of manifold pressure increase.
