w113 "Tall Fuel Pump" to "Short Fuel Pump" conversion

Has anyone tried this conversion?

I think it would be fairly easy to do, it seems that normal "CIS" fuel pumps would work just fine.

That won't really work. The original pump is low pressure and high volume. That CIS pump is high pressure. There are two styles of the original pump, the early tall pump and the later short pump. They are both high volume low pressure delivering about a gallon a minute.


Check The International M-100 Group for info on how to overhaul the original pump in the forum section under fuel system. Also check Welcome - Mercedes Benz 230SL, 250SL, 280SL Pagoda Group for more information. These cars use the same type of fuel system and electrics. Holley has a similar pump but the dimensions are different. I bought one from a speed shop made by 'Big End' #10150.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

Hi, great thank you.

Is there a website for those Holly pumps?
