Injectors

I just replaced my 75Hp injectors with my old Rv 275 that I just had rebuilt and when you rev up eng. and when it gets all the way down to idle it has a little burst or a little rev up to it. I hear com. rails do it. Any help would great thanks.

Well the common rails do it because of the extra fuel pressure in the rail blowing off... Takes a second or so for them to come down but as for the VP44 pump doing it... Ummm... Hmmm...

Man you love making me scratch my head on you fuel system problems...

Hey it dont miss anymore
I talked to Richard at coltrain inj. and his thought is it is electrical in vp 44.
I know this, fuel pressure is a little higher. Would that play a part in electrical part of vp44?

Fuel pressure and electronics have little to do with each other unless there is less fuel pressure than what is required... Cooling aspect...
