Older Beemers had drain plugs in the tank. I would just drain it, put in some fresh gas, like 3-4 gallons, and a can of seafoam , and see if she runs. Keep it simple.
it is a bmw i would not chance crap getting in. no year was given. and sitting 2 years means ethanol is in the lines and affecting all the rubber parts. and should be changed .
I agree ratrod. The ethanol could be the silent killer here. It doesnt play well with older seal materials in the fuel system.
I thought it was worth the mention to start the easier way in case there are some serious issues with the whole system the OP wouldnt waste a bunch of time and money.
The filter will catch anything before it, but there could be a ton of issues after the filter due to the ethanol, and just fuel degradation as well.
hey i am right their with you. i would go simple too. just would like to give all the options . i would clean and replace all that has to do with old stale fuel.
If I could afford a Beemer (which I cant), I could afford the premium fuel without the ethonol. Trouble is, I cant afford that either....
I would just replace the gas and see how it goes from there.
