Title: Looking for fuel pump alternatives
Post by: Eminent on March 07, 2013, 21:05:09

Hello folks.
My fuel pump (the taller one) is leaking a few drops fuel trough the small pipe.
I like to buy an alternative and found this one. (http://www.fuelpumps.com/mercedes-benz-fuel-pumps-c-54/mercedes-benz-280sl-fuel-pumps-c-54_494/1975-mercedes-benz-280sl-fuel-pump-6-cyl-28l-p-2355.html)
It should be correct for our cars, but the operating pressure is 73 PSI. The pressure from the original pump should be 16 PSI (0.8-1.1 atm), so says the BBB.
Can i install this pump without any problems, or should i search for a pump with less pressure?
Is there anybody who knows a (better) alternative?
Thanks in advance.

You can fit that pump without any problem. The fuel pressure regulator will simply dump the excess pressure back to the tank.
I've done it many times but with an even later pump from a 124, including the carrier.

My 250SL arrived running on a Carter fuel pump.
I am currently overhauling it, so I removed the Carter and got a brand new tall pump off ebay.

Eminent,
If you search the Pagodentreff.de web site you'll find that several members there use this pump and keep it in their spares box  for emergencies on trips:
