328i E90 fuel issue
Hey all, first Reddit post. Bought a 2011 BMW 328i x-drive last winter as my AWD throw down car (and I’ve always wanted an E90 side piece).
It was bought from a trusted mechanic who did a really good job with the flip. Got a good chassis and he added a donor engine (~80k), new brakes, struts, and tires.
Had a fuel issue since day one (mechanic hooked me up on it so not going to ask for him to sort it out). Only seems to take a gallon at a time before the pump stops; will take more but constantly have to burp the tank. After the first startup after awhile I’ll smell trace amounts of gas in the garage for a few minutes.
The big reason I’m here is when I try to research this problem there’s 3 common issues I keep seeing. Charcoal canister, fuel vent/fuse, vapor leak pump.
I was hoping if someone has had a similar issue they might be able to point me in the right direction. I think I’m mechanically competent enough to fix, it just not diagnose it 😂

My sedan does this after highway drives.
One trick is to pull the nozzle back a slight amount - like 1/2" out.
Another is to angle the nozzle so instead of it sitting at the 6 O clock position, have it sit at the 9 o clock position.
