Accufab's 2-Barrel Vent Tube Fuel Restrictors are designed to minimize or restrict raw fuel surge through the vent tubes without restricting the vent tube’s ability to vent.

Fire safety performance parts for Drag, Marine and Off-Road carburetor applications.

Easily install Accufab’s billet aluminum vent tube fuel restrictors (VTFR), a simple and inexpensive ball-check valve. Each VTFR will minimize or restrict raw fuel surge through the vent tubes without restricting the vent tube’s ability to vent. Also, they do not impact or restrict power in any way.

Application. Accufab offers three different versions for 2 or 4 barrel carburetor applications. Each version functions the same with matching internal parts. However, the off-road version differs by having a hose barb to utilize a connecting tube between the vent tubes. The Marine version is slightly elongated in comparision.

The Drag version is anodized black and is intended for drag or dry lakes racing but does not have a hose barb. The Marine version is anodized blue and meets USCG requirements. The Off-Road version is anodized black and may be used for drag or dry lakes racing. Also, the off-road version has a hose barb to utilize a connecting tube between the vent tubes.

(*Note: The off-road version was previously anodized red, but this color has been discontinued.)

Note:

1. 2-barrel applications use one VTFR
2. 4-barrel applications use two VTFR's

Installation: Please see Tech Support for required vent tube modification and installation instructions.
