I can't answer your question, but I'm pretty sure I recall that there were two part numbers for 1989-1995 trucks, but it had to do with matching up the right sending unit to the same guage panel, since two suppliers made gauge panels for Toyota and apparently, you had to have the same maker's sending unit to match up with the gauge. I don't recall there being a difference between engines, but I could be wrong.

You could call a dealer parts department and ask if there is more than one part number and if it distinquishes between V-6 and 4 cylinder.
