Hey... anothor diesel tired guy..

I am on the way to swap a drivetrain out of a K1500 1997 Tahoe into a 1997 K2500 6.5TD Suburban. But I will use the 5,7 Vortec and it's original 4L60E, I only swap the transfercase from the 4L80E to the 4L60E. I try to use the fuel pump assembly out of the Tahoe, but I am wondering if it will fit in the fuel tank of the Suburban?
Did you recieve any more info on this?
