MSW Refueling Dry Break Probe Guide

MSW’s Take: Refueling during a race is a critical moment that can often mean the difference in a finishing position.  We’ve sometimes struggled to get our fuel probe aligned with the receptacle on the car, leading to longer stops and spilt fuel. 

These fuel dry break guides have been implemented by some factory race cars recently, so we decided to design a universal version for anyone running an ATL-style 2.25″ dry break receptacle***. 

The guide has a funnel shape to help center your refueling probe and allow for easier and quicker connections.  It’s machined from a solid piece of Delrin, which is a high performance acetal resin with exceptional wear, impact, and chemical resistance.  It will not damage your expensive fuel probe, even after repeated hard and fast engagements.

We designed this guide to be compatible with the ATL RE182 2-1/4″ Dry Break Female Receptacle***, but it should be compatible with other brands that use the same bolt pattern (9 holes on a 109.2mm PCD ~4.3″).

UPDATE: We now have a version to match the other 9 bolt ATL dry break that uses a 4″ (101.6mm) PCD pattern.  This size is more commonly found on factory built GT4+ cars from Europe, as it’s the size that ATL Ltd. (ATL UK) offers.

To determine which size you need, first make sure your receptacle has 9 holes.  Now measure the distance between two adjacent holes (on center.)

101.6mm PCD: Distance between adjacent bolt holes: 34.7mm / 1.37″

109.2mm PCD: Distance between adjacent bolt holes: 37.3mm / 1.47″

The guide is secured using three included M5 socket head bolts* which match the PCD of the standard ATL 2.25″ receptacle***.  Just remove three of your existing bolts to mount.  The backside of guide has machined out pockets to provide clearance for the remaining mounting bolts.**

*The included bolts should work for most applications, but depending on your fuel receptacle installation, you may need to source shorter or longer bolts.
**The mounting bolts that secure your fuel receptacle must have small button heads in order to clear the bottom of the guide.
***In some literature these are referred to as 2″ receptacles, as that is the size of the actual probe, but they use a 2.25″ hose barb.
