I'm not sure if this is true of all Comp fuel pump pushrods, but I was told by the guy I deal with there that they are made by Trend.

So, it's not it came from some no name supplier.

Apparently getting the material/hardness just right so it doesn't wear out, and doesn't eat the cam eccentric is a secret.

And I stand behind previous statement about them being oversize. If that's true...... It's just dumb.
