Parts made in China? Ohh wait...this comment might belong into purple.look at old le mans pit stops, this was a hickup, stuck qd disc, residual psi in tank, vent not venting quick enough, dirty k&n fuel vent filter,topped off fuel in filler neck pushing Back out fill qd, looks like pit guy tapped it,& it re seated closed,ready...... next......... theory......GO!
if the vent is plugged or air movement is slowed by filter clutter, and you use a pressurized system, the bladder still expands and does that.
This seems more and more like the Redhead Drybreak is the common denominator when it comes to fueling incidents with both Gravity-fed and with PP fueling systems.
A more robust sealing system would help IMO.
Both the valve on the truck is spraying fuel and the valve on the hose is also spraying fuel. Why are they both spraying?This is a dual hose system. The tank is vented out the second hose. If it's working properly the tank vent on the truck is not needed. All the spray happens after he pulls the hose, 100% seal issue in the redhead.
