sounds like to me that the timing on the injector pump is a bit advanced. I'm not sure how it works on the RFs with the front mount pump, but on the rear mount pump there is a set of marks to line it up, then a fine touch adjustment for it's orientation. If it runs but rough I'm willing to bet that the teeth on the pump/belt are lined up properly, and it just needs a slight adjustment (like advancing/retarding a distributor.)
