Quadrajet Anti Drainback kit.
Does your Qjet have to crank for an extended time in the morning, even though the choke is working? Your fuel bowl may be draining back out the needle and seat. This causes extended cranking time as the fuel pump refills the fuel bowl so your engine can start.
This Quadrajet Anti Drainback kit includes a new fuel filter with checkvalve, and a non-windowed .132 fuel inlet needle and seat to keep fuel in your fuel bowl.
The non windowed needle and seat raises the minimum fuel level to to the top of the inlet seat to minimize drainback. Its larger than stock .132" inlet refills the bowl quickly.
The fuel filter check valve provides a stop for any fuel that happens to make it out of the fuel bowl past the inlet needle, but opens to flow freely INTO the carburetor under normal fuel pressure.
PLEASE NOTE: YOU MUST SPECIFY A SHORT OR LONG FUEL FILTER
