Guys swear by these, no gas smells in their garages that an open vent often allows.
On the return, when the early EFI swap guys were on the power tour in the early 2000s, many had hot fuel issues due to returns from the engine. it was causing fuel pump cavitation. that is when the corvette fuel filter with the regulator came into vogue. Note Chevy doesn't return hot fuel back to the tank.
OEs do things for reasons. |
Prior to that vette setup they did. Don't recall reading of issues with stock stuff
My pump pulls a vac on my fuel tank with just one 6an vent line, so next tank iteration will def have a larger vent in place. Along with a fuel return submerged.
