The same Bosch electric pump was used for all MFI engines, '69 thru '76. The fuel delivery rate was 125 liters per hour, and 900 - 1000 cc output in 30 seconds.

Ed,
Are you perhaps asking about the MFI INJECTION PUMP specs????

The injection pump is what I am looking for the specs. Trying to see if they are that much different. ED |

Oh, they're different all right.. Warren may have the specs, or another of our gurus.. Gus Pfister at Pacific FI is the real expert here, I believe...
I don't know personally, but I know an E runs crappy with a T pump...don't ask. BTW, does anyone know if Gus is training an apprentice to carry on the tradition when he finally decides to retire??/

ED,
There are different output curves plotted in terms of output volume in cc's per injection stroke vs rpm in the factory service manual, and perhaps in some of the Pelican reference documents.
