LS Swap Fuel System Help

[Haggar]

On mine, I run an aeromotive phantom fuel hat/module with a Walbro 255.

Plumbed like:

Fuel out -> Corvette Regulator - > Fuel Rail
Corvette Regulator Return - > Return fitting in fuel hat (inside the tank, this is piped down to squirt back into the module, low down to minimize aeration)
Fuel Hat Vent -> Looped line with a filter/rollover valve, located high up behind my left tail light

All of my 'stock' vents are capped. Note, this is an aftermarket Poly tank, but it is for the Jimmy.

As far as I know, the fuel cap is stock.

No issues with this setup in the last 3 years.
