The last model year for the 7.3 was 2002, then it went to 6.0 then to 6.4
1994-2003
7.3 Liter Turbo
In a 2004 Ford F-250 : Gasoline engine choices ( 5.4 liter V8 and 6.8 liter V10 ) Diesel engine ( I believe that is 6.0 liter )
The diesel engine available in the 1984 Ford F-250 is a : ( 6.9 liter / 420 cubic inch / V8 diesel )
The optional diesel engine in an '04 F250 Ford is a 6.0L V-8 Turbo Diesel made by Navistar (International)
It could either have a gasoline engine or a diesel engine
I know that the 2003 ford f250 diesel was what they call the lemon year. They swiched from a 7.3 to 6.0
A 1990 F250 with a 7.3 liter diesel in it should get roughly 20 miles per gallon. This will decrease if you do not regularly have maintenance done on the truck though.
As you are looking at the front of the engine, it is located behind the vacuum pump; bolted to the block.
I was looking at the Ford parts website and it shows : For a 1984 Ford F-250 : ( the 6.9 liter / 420 cubic inch / 8 cylinder diesel engine was available )
