2590 and 2670

[J-J]

Is there a difference between a fuel pump from a 2590 and one from a 2670? Are they both 10mm? Which is better?
thanks for any help

Should be different, but I think only in the settings. 2590 is 180hp and 2670 is 220hp. I know the intercooler gives the 2670 more hp but I believe the pump is turned up as well.
No mounting or external differences as they are both 504 engines. Hopefully others will give you more info.
