ok then how about this then... According to carter fuel pumps and their part application guide it says that the fuel pump for a 1990 ford ranger part number P74528S this part fits rangers from 1989 through 1997 as well as for the 2.9, 2.3, 3.0 and the 4.0. would it be reasonable to assume that the gauges from these vehicles will work with this pump/sending unit. what I want to know is there a way to modify my dash gauge cluster to accept the cluster out of an 89 and up ranger into my 84 ranger standard cab? Or will the gauge out of an 86 87 or 88 ranger correspond with the new pump and sending unit? I am assuming that ford did not change the values for the sending unit and the gauge.
