2003 Workhorse Chassis - Which Fuel Pump?

[keninvic]

I am trying to figure out which fuel pump I should order for a spare. If anyone specifically knows which number I should get, please help.

What I have read elsewhere in this forum:

'02 and '03 Chassis uses a #25315352
Apparently, 25315352 superceded the 25178125, but I dont know what the difference is.

I found one XREF for 25315352, A CARTER P74758M

Previous to that:

25178145 = Delphi FG0064
25178125 = Delphi FG0061

Will the 25178125 or FG0061 work on a 2003 Workhorse ?
My VIN is: 5B4MP67G833375789
