Fuel Pump and More PLEASE HELP

Hello All,
Very soon I might be buying a used 2005 BMW 325i, this being my first e46 purchase I am thrilled However, I'm buying it without a functioning fuel pump cause I heard from you fanatics it's easy and inexpensive fix. Anyways, the seller tells me it ran and drove great before and everything that you want to hear and more. But, I'm still a little hesitant because he mentioned as is, so any advice with future problems or problems that can be stemmed from the fuel pump that can affect the longevity of this purchase? Thanks

Before you buy the car... have him send you a picture of the engine bay. Tell us if it's an M54 or an M56. If it an M56 then do not buy it

It sounds like it is a non running car. I hope you are getting it for salvage price since there may be plenty of surprises waiting for you when you get it running.

It's easy yes... but not the M56 engine which has the built in fuel pump.

The problem isn't the difficulty level to replace the fuel pump, it's the fact that it's not running. A non-running car is a parts car, and you should pay that sort of price for it.

Assuming it's in perfect condition, with low miles, not a penny over $2000. If it's not in perfect condition, then not a penny over $750. You can't consider this a functional car until it's running. Perfect condition being a car that has been maintained so well that you can't tell it's not new.

If he wants to sell the car, he needs to replace the fuel pump, or get it replaced, and then demonstrate that the car is fully functional.

Buying the car in this condition, for anything near blue book, is akin to responding with your credit card number, social security number, and mother's maiden name to that email from Nigeria that's sitting in your spam folder.

I like the "parts car" analogy!

Or you show up with a fuel pump in hand and install it after negotiating the price, but not handing over the cash.

Install the fuel pump, and if the car runs great, if not, put the original pump back in and keep your new pump for your next project and walk away.

Someone good can replace the fuel pump in as little as 15 minutes, a novice should be able to do the job in 30 minutes.

For $130, you can get a pump from www.oembimmerparts.com.

Cheap insurance. But also as mentioned, MAKE SURE the car is NOT an M56 SULEV. If it is, keep moving!

experts:

I need to change the pump,
which one you think would be easier to swap and give right gains on mid tuned engine
M3 oem or Walbro aftermarket (in this case which flow rate to choose from)

pressure regulator? mod mine or get a new one with more psi?

thnx
