Many endurance racing organizations require a fuel flow restrictor in your dump cans to slow down pitstops. These restrictors must be a specific size that is checked for compliance at the track. They must also be made of a fuel safe material, and ideally they flow better than just a generic orifice.
These restrictors are machined from a solid rod of gray PVC, which is completely fuel safe.
We tested four different designs to find the fastest flowing profile, coming up with one that on average flowed 3 seconds per 6 gallon jug of fuel faster than any other alternate design.
- Shoulder machined on end to keep restrictor from lodging itself into dry break
- Size engraved into lip of restrictor (MSW-FR-010= Fuel Restrictor 1″)
- Gray PVC material is fuel safe for all common gasoline blends
- Fast flowing design that is compliant to series that require a 1″ restrictor.
- Will not soften or deteriorate like 3D printed restrictors.
- Compatible with ATL, Red Head, Allstar, and Fuel Safe 2.25″ probe dry breaks*
*Should fit any dry break probe with a 2″ ID. The 2.5″ probe dry break typically has a 2″ ID and is designed for 2.25″ ID hose.
Compliant with WRL Rule 3.j.:
The narrowest point of the hose, nozzle or funnel spout must be no larger than 1.000” inside diameter and made of a solid material. Fuel jugs determined to be noncompliant via go/no-go gauge will result in a 1 lap penalty per fueling stop from the beginning of the race until the jugs are in compliance.
