Holley Tech Tip

[skrews]

I do a fair amount of Holley freshen up jobs for people, and one of the things I find that many miss are warpped accelerator pump housings. My simple fix is to just file them flat. I know its not rocket science, but its amazing how many leak problems this often over looked part has solved.
I realize its a no $hit kind of thing to many, but some might benefit from seeing this.

The Holley torque spec for those little screws is low, folks often over tighten them.

Yep, and when they leak some people just crank them down even more.

Yeah those screws have a very light torque spec. I don't know what it is, but it ain't much.

And only use the black Holley diaphram in my experience. The cheap rubber ones just fall apart on pump gas.
