Fitment question (e30)

[04nhbpep3]

Will a 318 fuel pump and filter fit on my 84 325e? I've looked everywhere and can't find anything on it.

check realoem?

check realoem?

What is that?

I believe the 318/early 325 pumps are the same. Check the part numbers between the 2 chassis.

Plug in the last 7 of your VIN here - http://www.realoem.com/bmw/select.do

I don't have the car with me so I'm not sure of the VIN. Anyone with an 84 want to donate theirs?

You can guesstimate by year if that's the case.

100% certain the fuel systems are the same. The cars only differ int the engine bay. Everything from the firewall back, fuel system wise, is the same.

Positive? Lol. I don't want to drop this money and it not be the same, lol.

positive man. go for it.

The filters are the same as well as the supply system. There would be an issue if your 318/325 was a later model but it isnt. As long as no one has retrofitted or updated anything in the fuel system, then everything from the 318 will work in the 325 and vice versa.

I should have probably noted this in the first post. the 318 is a late model (91). I'm guessing that means that it won't fit at all, haha.

Sorry about that man. The problem with the early model fuel pump unit is that the fuel pump and level sender are on the same unit and the early system has a lift pump and a high pressure pump. In a late model, they have only one pump and the level sender is separate from the pump assembly.

The 318 pump can work but it takes a lot of retrofitting to make it operate correctly. You would need to delete the external pump and lines then trim the pump bracket that holds the pump inside the tank. Lots of work and in the end, you are still replacing the pump with a used piece.

Bummer. So what all pumps would work? You seem pretty knowledgeable so what about starters also?

[E30_fiend]

any early model pump would work for you. So a pump from any e30 between 83 and 8/87

[E30_fiend]

as for the starters you will just need one from an early model m20 car. The m10 starters wont work and I believe the late model m20 starters have a one extra wire if I remember correctly.

Thanks man. I really appreciate the help (and saving me from hours upon hours of research, lol)
