My son wants to install a fuel cell on his 82' 320i with the mechanical injection. The fuel pump looks very old and I told him to look at replacing it until I saw the prices....
Question: Is there any reason he cant go with an aftermarket 70psi fuel pump? The factory dual pump setup seems cheesy and expensive.
Thanks

I have an external inline bosch motorsports fuel pump for sale if interested. Let me know.

$105 for a Bosch replacement seems reasonable to me

Thanks all for the feedback.
Thinking of going with a higher flow FP, I'm assuming that any extra fuel will bypass the distributor back to the fuel cell.
I'd grab Bassboys pump, personally.

I still have it if interested

Since the earlier post, I'm now running Bosch Turbine Fuel pump-69430 which is the newest tech on the market with added advantages over old tech fuel pumps , to get higher fuel pressure to the fuel injectors before gas return thru the fuel pressure regulator one adds shim(s) to the pressure regulator in the Fuel Distributor-see faq's-also take into consideration enrichment/lean cycles and its effect on fuel pressure to the fuel injectors, Hayg is a cheaper option, I recommend Bosch 69430 and FCPEuro-with lifetime warranty. Its your choice.
Heres my post on this in case you all missed it.
