Needle and seat .135 orifice with window

Fit perfect and worked excellent to eliminate fuel flowing issues at full throttle

...really nice oversized needle/seat for performance upgrades...plug and play.

Nice to be able to upgrade to a slightly larger part on certain applications.

I have a 61 Falcon Gasser that I run a 327 SBC with a THM 350 automatic. I'm using a early quadrajet. Was having problems running out of fuel at the top of second gear. The needle and seat were of the generic kind with no windows. Installed the .135 with windows and the problem is gone. Great product.
