Problem filling stock tank?

[Pranav]

I won't name names but there are plenty of others here that have a straight hose going out back to a breather as well.

My overflow tank with 1psi valves stopped it from from spraying out all over the track and kept the situation pretty well contained for the 2 events I ran it. Only ripped it out for MSRH because I thought it was causing my fueling issue, which it wasn't (I manually flip a big ball valve to make a straight, unrestricted vent which bypasses all that crap when fueling in the pits).

Fumes from a hot tank on a return style fuel system have to go somewhere, they don't just disappear into thin air. Do you know where your tank fumes are going?

Only other solution I could think of is we all start running the factory EVAP hardware again.
