I have an 89 f350 the date on the door tag is 09/88 the valve cover and door tag say it's a 7.3 but it's won't fit the 7.3 fuel filter only the 6.9 has the old style start relay and most confusing is the head bolts are 7/16 not 1/2 capfuls this be a Frankenstein from the factory or redneck engineering
