Vintage Fuel Pump - 64 Mercedes 220seb
I need an electric fuel pump to fit a fuel injected 64 Mercedes. Is there a generic pump that will work or am I stuck paying for an OEM Bosch unit with a starchy price of between 600-1000 bucks?

It's been reported in this forum that a Holley electric pump works. If you do a search you can find it. The main requirements are volume not pressure.

Early EFI pumps work.. early 3.5/4.5 EFI and 116/EFI chassis. Just have to do some mount changes.....Don't use the later CIS pumps.

As it turned out, I was able to open the old OEM pump up, do a little minor cleaning, hook it up to a 12 volt source, and it started spinning. After that I reistalled it, and it is happily pumping fuel. Thanks for all the tips about a replacement pump. I'll file that info away for future reference.

That is what most guys do..they just get full of old fuel.
You can still buy a service kit for them from SLS . The kit just contains the gaskets/O rings and a set of brushes...pretty simple to rebuild.

The later CIS pumps will work too. Just don't get the ones where there are two pumps in tandem.
The older MFI cars want fuel volume, not pressure. The setup of fuel flow and return will ensure that, even with a CIS pump. There are a few parts you can pick up for about 30$ to mount the pump efficiently on the car. They're mentioned in a thread at www.sl113.org that describes the conversion. -CTH

Dual electric pumps
For reliability after my original fuel pump failed, I mounted and wired another pump in parallel once I resealed/repaired the original. Now if I sense a failure, verified by an installed fuel pressure gage, I just flip a switch to start the standby pump. I also have a 1963 220 SEb.

The problem w/CIS pumps is too high a pressure for the MFI system..they will work, but not well. You can have the same problems w/cis pump as you would if you had a plugged return line.
Been there. You do not want a pump that has anything over 3 bar pressure. CIS pumps run higher. That is why EFI pumps are the best recommendation. Whatever pump you choose , you want to do a fuel pressure/volume test after install. You are looking for 13-15psi with 1 ltr/15 sec. flow rate.
